I think there is a potential problem with people pulling into the fairly large gap that is left, meaning quick deceleration and minor panic, and compensation driving and braking.
I’d like to see how self driving car logic resolve problems such as changing lane to overtake someone going at 50mph, which someone storming down the faster lane at 90mph.
I assume it would be programmed for the safest possible solution, which is to stay 3 car lengths behind the 50mph driver until they finally turn off. -
In heavy traffic i knock the gap down to 1 second to avoid people cutting in, way too short for human reactions but this is the gap most seem to drive at in congested traffic. Given the number of measurements a second being taken and the car reacting quicker than me even noticing a change in speed by the car ahead I’m happy to trust the robot overlords with this. It also allows me to focus my sight further up the road for what might develop rather than the bumper of the car in front.
This.
My car already does this (without being able to remove your hands for more than 10 seconds) and it's great. It keeps a much safer distance to the car in front than 90% of human drivers, maintains impeccable lane placement and reacts more quickly than I can to emergency situations.
I too welcome the robot driving overlords.
