Robocars - Autonomous Drive, Self-driving, Driver-less cars

Clearly never met an Audi, BMW, Merc, Volvo, Range Rover driver.

Don't confuse aggressive or non-cooperative motorists with unpredictable drivers. Its like with taxis.. You can typically predict how a taxi will (mis)behave and select a strategy. When you hear a car behind you starting to rev their motor you know that they'll try to pass-- at any cost-- to rush to be first at the red light. When you approach an intersection and you look for eye contract with the driver.. you assume that they might try to ignore your right of way and not yield but also that they don't want to get into an accident.. Part of defensive driving or cycling is about trying to estimate all the possible moves of all the traffic participants. Its built upon a number of learned behavioural models and value expectations. You examine and gauge each traffic participant as to their "nature". If you notice a car being pushy you select a different set of responses than when you notice that the car is being cautiously driven. When, for example, you see people steering with their body vesus their arms you can assume, for example, that they might take a curve like a small child in a bumpcar.. When you see a women in a Cayenne-- having observed many women in Cayennes-- you have a model of behavior..

Ultimately where this chain of arguments lead is to the need for dedicated self-driving roads, resp. lanes, where they are amongst themselves, can communicate with one another and as a swarm optimise their movements.
