I think it works well on city streets. I fully expect to take over at times. The way I look at it is per the manual I am fully responsible for the control of the car so it doesn't matter if I use AP or not on city streets. I am still the one responsible.
It matters in the sense that any time it "works" on city streets is pure accident.
The inherent assumptions of the software are:
All traffic is going the same direction
All access on/off the road is limited via ramps
There are no intersections and
especially no cross-traffic (ignoring this is what killed both idiots who drove under tractor trailers on autopilot)
Using it when those things aren't true means you're just randomly hoping none of those things come up on roads where they inherently come up.
However looking at how it performs it will have to be a huge update
It would have to be an update that actually is intended to handle intersections and cross/oncoming traffic.
Which the current SW isn't.
What the current SW does in those situations tells you
literally nothing about the ability of future software in those situations.
I would expect current software to be a lot closer than it is.
Which is a mistaken expectation, since
nothing in current code (other than the 'warning you are about to run a red light') is relevant to city driving.
It's not that "their current city driving code isn't great"
It's that "their current city driving code
does not exist"
It will in a future version- and again what todays SW does tells us
nothing at all about how well it'll work.
. If they are as close as they are implying why haven't they gradually improved it over time.
How do you gradually improve something that doesn't exist?
City driving code is for HW3 using a much larger, more advanced, neural net.
Everyone, even HW3 cars, are still running the HW2.5 "only understands limited access one-way highways" AP code.
