Re: In the UK...
Err... Autonomous vehicle designers have an awful lot of real world practices to learn.
Never switch on your headlights when visibility is reduced. Sidelights (and yes, I do own a vehicle with real sidelights and trafficators) or parking lights (as our colonial cousins call them) suffice for all driving conditions.
When instructed to self-park, autonomous vehicles should hunt around for a space within 100 metres before placing themselves on the pavement.
Vehicles with four circles on the radiator grille are exempt from traffic laws. Even so, brave it out in chicken run games when you identify the four circles.
Hazardous load warnings on the rear of lorries exist to discourage tailgating. Most tankers on UK roads transport molasses. What's all this tosh about oxygen cylinders, too? Oxygen is just air, innit?
After pulling over for an ambulance or fire tender to pass, appropriate action is to belt along the road after it.
When approaching a light controlled pedestrian crossing (a pelican crossing) on green lights, always place your car half way across. You never know when a car from an alternative universe will be teleported into the gap in front.
Indicator lights (including trafficators), when human operators can be bothered, are used to signal change of direction to other vehicles. Pedestrians and cyclists are totally unaware of their existence and may be ignored.
Overtaking manoeuvres require a 1% speed difference. That's why the middle lane on motorways exists.
So, more seriously, how many of those scenarios are being tested by autonomous car developers?
