Having drank the koolaid, I am hopeful for great things. Eventually. In the meantime I need to manage my expectations!
Having lived in San Diego for 15 years, I know how streets are set out, road marking conventions and driver behaviour. They are all very different from my experience of French, German, Italian and UK roads. In the UK, city driving needs a lot of driver eye contact. Passing on city streets lined with parked cars requires regular driving against oncoming traffic on trust that those drivers will pull in to a gap to let me pass.... while also expecting the same of me. Towns and villages in rural France and Italy hardly have room for one car to squeeze through in places. Roundabouts. Well, in the UK I reckon most drivers know of at least one and probably several multi-lane, multi-road roundabout that a) they don't really get how the road layout and lanes are supposed to work and b) hate driving on and may be scared of! And roundabouts range from a worn out smudge of paint to a full art installation 20 feet high or even multiple small roundabouts set out around one or more larger central roundabout.... and roundabouts are everywhere.
Toll booths.... 2 freeway lanes with markings (in France) turn into 200 feet wide unmarked tarmac with 20 toll booths, manned, unmanned, electronic payment.
Many streets rely on reflective markers on posts to highlight edges of the street, sharp turns, etc. Auto headlights can't identify the reflection as not being a car coming towards you so turn on and off high beam.
Bus lanes, cycle lanes, zebra crossings.... I mean the list goes on and on. And these car movements are between zero and 10 mph where the car already struggles to make smooth sensible motions. The constant contact with the eye of pedestrians and other road users needed to navigate intersections safely and negotiate passage.
Conventions like flashing headlights can have completely opposite meanings in different circumstances.
In France it is common to leave a turn signal flashing as you drive along in the passing lane on a freeway to say (as only the French can do) 'get out of the way, I'm more important than you!' But it does also signify that the driver intends passing some more cars before maybe pulling in to a slower lane.
This is all fundamental to basic driving on city streets an freeways but not handled in AP at all so far.
