Rivian's TM-B electric bike

There's literally thousands of e-bikes with touch screens and it would be unsafe for a bike of this weight to have anything other than hydraulic disc brakes, which are the standard for just about anything that isn't a road bike these days. Locator also pretty common even on $1,000 ebikes.

But yes, other stuff seems to be features for the sake of features.

E-bikes with properly adjusted mechanical disc brakes are perfectly safe, and mechanical brakes are easy to adjust yourself without the need to take them to a bike shop. It's the discs that are important -- not whether they are mechanical or hydraulic.

A touchscreen on a primarily-outdoor device makes no sense to me. It's just a single point of failure for fanciness. Transit safety should be taken more seriously, with controls you can operate by feel, rather than vision. It's not important if lots and lots of companies include this single point of failure.

Edit: also, don't capacitive screens kinda suck if they get a little wet? like what, you just can't use the screen controls while it's raining without risking unlocking your seat 40,000 times in a half second due to a stray raindrop sitting on the screen? Feels like resistive would explicitly be superior here. You probably don't need huge accuracy for what should ideally be a spacious display anyways.

conversely hydraulics don't need adjustment

...except when they do. If you get a leak or an air bubble for example and have to flush the system, you'll need a trip to the bike shop.

If you put miles on your bike and ride hills, you'll spend way more time fiddling with an allen/torx on the inboard pad or the adjustment barrel on the cable as your pads wear. The bleeding procedure for hydraulics is for sure messier, but still very doable in 5 minutes. When you do have air in the system, pumping the lever a bit gives you back some braking function.
