Waymo granted permit to begin testing in New York City

Granted, NYC is the biggest city in the US, so maybe that sort of reaction is more reasonable there than when people in Dallas or Boston do it.

Why does having launched in other cities matter if the new city brings up things that none of the other launched cities do?

For example the first thing I can think of new for New York is snow and ice.

It's my understanding that self-driving cars don't really account their acceleration and braking for roads that could sometimes be very slippery due to snow and ice.

New requirements come up all the time in technology. The existence of a new requirement isn't in and of itself justification for skepticism - is there a particular reason to believe that Waymo is not capable of solving for the new requirement?

The answer may be yes, but simply "ahah! It would need to do [new thing]!" is insufficient. "[new thing] is likely intractable because [reason]" would be more justification for skepticism.

Sure, but like above - is there a reason this is an intractable problem?

I'll throw this out there: your human-driven car already accounts for acceleration and braking on slippery roads, without the need for the human. Traction control systems and electronic stability control systems exist! They're in fact incredibly common on modern cars.
