If you watch the videos more carefully, you will notice the people who speed by at 85 MPH later enter the screen again, because that is the nature of freeway traffic.
I predict that a few hundred of these on the road will measurably improve safety and decrease severe congestion by being that one sane driver that defuses stop-and-go catastrophes. In fact I think CHP should just contract with them to pace 101 in waves.
A slow fleet of Waymo’s will impact your average 5-10 over same as your 20 over, and that’ll collectively impact traffic.
The implicit assumption you and many other in tech share is humans must adapt to the tech protocol, and not the other way around.
After 20 years of growing negative externalities from this general approach, which I see baked into your comment - are we seriously about to let this occur all over again with a new version of tech?
Fool me once, fool me twice… I think we’re at fool me 10 times and do it again in terms of civic trust of tech in its spaces.
Of course, unlike the normal car break-ins here, the cops might do something about them.
"Waves" are really what we would want them to prevent: https://en.wikipedia.org/wiki/Traffic_wave
The autonomous cars can prevent these waves from forming, which would get people to their destinations faster than speeding.
There are many instances where the entire mass of traffic across three or four lanes is 10-20mph above the stated limit, e.g., going 75-85mph in a 66mph posted area.
It may not be legal, but it is reality. And when it is everyone, it is not only "aggressive" drivers. It is everyone. And one driver thinking they will change the situation only makes it worse.
If you are going 20-30mph below the speed of traffic you are at least as much a hazard to yourself and everyone around you as going 20-30mph above the speed of traffic, and the stated speed limit has nothing to do with it.
Going substantially slower than traffic, even in the slow lane with flashers on, nearly all of the threats and actions are overtaking you and coming from behind you, meaning to see and react to most of the developing situations, you must be driving through your rear-view mirrors.
And the situation you create can be very deadly, as one car can change lanes to avoid you, revealing you late to the next car, which barely changes lanes, and further reduces time for the next, who hits you and starts the pile-up.
It is not only their problem, it is yours too. Sure, you may be legally in the right, but you have still caused yourself to get hit.
What my grandfather explained to me is still correct:
"You never want to be dead right."
Though I’ve heard people treat it differently in the US
Also, if the Waymos are following the laws, and that causes problems... then maybe those laws should be changed? Especially if most drivers already don't follow the laws.
If "we'll have too many cars on the freeway following the speed limit" ranks as a serious concern, I think we've really lost the plot.
I recently drove by a fatal accident that had just happened on the freeway. A man on the street had been ripped in half, and his body was lying on the road. I can't imagine the scene is all that unlike the 40 thousand other US road deaths that happen every year.
As a driver I'm willing to accept some minor inconvenience to improve the situation. As a rider I trust Waymo's more than human drivers.
Plenty of people do not follow the rules about staying to the right.
I've lived in a couple of places where going the speed limit is a whole problem that can cascade outside of just yourself. There is an argument to be made that perhaps then the speed limit shouldn't be that low, but in driving safety is far more important than legality. It will be interesting to see how Waymo handles these realities when it gets to those areas.
It makes less sense in an urban environment with 5 or more lanes in your direction. Vehicles will be traveling at varying speeds in all lanes, ideally with a monotonic gradient, but it just doesn't happen, and it's unlikely to.
In California, large trucks generally have a lower speed limit (however many trucks are not speed governed and do exceed the truck limit and sometimes the car limit) and lane restrictions on large highways. Waymo may do well if it tends toward staying in the lanes where trucks are allowed as those tend to flow closer to posted car speed limits. But sometimes there's left exits, and sometimes traffic flow is really poor on many right lanes because of upcoming exits. And during commute time, I think the HOV lane would be preferred; taxis are generally eligible for the HOV lane even when only the driver is present, but I don't know about self-driving with a single or no occupant.
(also it’s kind of amazing that 5 parallel lanes is considered normal in the US… I think the most I’ve ever personally seen in the UK is 4 and that’s only on very major routes, and we don’t have any exits on the wrong side of the motorway)
If you actually thought adoption would benefit us on it's own rather than seeing it a roundabout way to enforce rules that you want to see enforced without buy in from the public you'd want these cars to behave in a way that makes it easier for them to exist in typical traffic.
Normal human drivers tend to lift off the gas and only brake when they decide that just lifting won't do.
I often wonder about laws that are ostensibly there to prevent dangerous actions, about whether they actually help prevent dangerous driving.
This guy analyses tailgating: https://m.youtube.com/watch?v=6n_lR09sjoU Awesome software although he seems biased (e.g. no mention of pedestrians), but he does say that tailgating is much more dangerous than speeding.
I'm interested whether cameras will start to catch dangerous drivers. I regularly seeing drivers do very dangerous things. Yet we have no easy way to train them (for those that care but are unaware), or catch them (for the antisocial that don't care).
Not necessarily. I've seen things like the left two lanes at free flow (speed limit or above) and the right two lanes at full congestion (~ 10 mph), and the middle lane(s) somewhere in between. But then you also have sometimes where the left lane is only doing 60 for some reason, but the next two lanes are at or above the speed limits. It's a complex system.
Wrong side exits for interchanges between highways are common, depending on site details and relative flows. When there's congestion on a left exit, you then get situations where the right lanes are flowing faster than the left lanes (sometimes much faster). I don't think interchanges as left exits are necessarily awful.
Wrong side exits to surface streets have been discouraged for new construction for quite some time, but there's a fair number of "legacy exits" in some areas. They're not so bad when there's only two lanes in your direction; but when there's been highway expansion, it can get pretty hard to use. And inevitably rebuilding to current standards would causes a lot of confusion and delay, it's postponed. My exemplar of the worst left exits, the Milwaukee Zoo Interchange, was rebuilt in 2012-2022 and I can't find pictures of what it was before, but you had a sizable interchange with right and left exits to other highways, combined with several surface street exits and entrances on both sides, and I think two through lanes. It was a mess.
Don't EVs light up the brake lights when regenerative braking engages?
I've definitely observed Teslas coming to a halt, and the brake lights only kick on at the very end. I don't know how widespread the problem is, but it's very annoying.
I used to drive 20 under all the time (I achieved 57mpg once doing that) - but since this was an empty rural highway the few cars that were around saw me well in advance and moved over and passed without a problem.
My dudes, I have been driving the speed limit, even on freeways, for decades.
Nothing bad happens. Your car doesn't explode. You don't instantly create thousand-car pileups.
You get passed slightly more often than when you are speeding. You pass fewer cars. You get to your destination a few minutes later.
A car going the speed limit on the freeway is not a problem.
Second, it is a widely known issue, that a slower mowing car is causing ripple-like delays far from the car itself. For example when a police car is driving inside the traffic flow. But if most of the cars are following the rules, like 95% of them, then one law abiding Waymo would fit just fine. In EU, with the deluge of speed traps and mobile patrols, most of the cars are driving under the limit, and honestly it feels fine. I'm originally from a country where +20 above was like a norm, and fast cars were +40 or more, so adjusting to EU took some effort. But now I don't even feel the need to speed, especially if it is 140km/h highway (86 m/h)
Heck, it wasn't even all that rare for it to take me 45 minutes to go 5 miles on 101 from Rengstorff Ave to Willow Rd in the Bay Area in 6pm rush hour just because of the exit.
It even once took me 2h to make it from Candlestick Park to the 101 after an NFL game.
So yeah, maybe 2 hours for a few miles isn't quite right, but I've experienced daily counterexamples to your 20mph number too.
If you're annoyed by the braking lights on a Tesla, it's because you're following too (dangerously) closely.
