It's also really good at 25Mph - when the roads are not busy in my area I take it out and drive slower and on curvy roads that might be normally 35-40 I slow down autopilot to say 25 and it's really good. At speed there are still a few turns it misses. A year ago at speed it couldn't do even half of what it can do at speed today. So it's also improving with every update

Google went for a 25 mph top speed for regulatory reasons (the car is basically classified as a golf cart that way), not for technological reasons.

I would be absolutely fucking terrified to engage autopilot at all in Mountain View, let alone at 25mph.

It's a great feature, but it's a great feature for boring driving.

> it's a great feature for boring driving

I'd much rather have a "boring" driver on the road than deal with aggressive drivers.

Agreed. My point was that it doesn't deal well with "exciting" driving. Given a long stretch of mostly empty interstate highway Autopilot is great (and keeps it suitably boring/low stress). It does miserably in suburban areas (let alone urban areas).
