I suspect 5 years will be more like 50
At the moment the so called intelligent cars, have to have a team of people poring over data, preparing specific routes for each journey, making sure that there no nasty unexpected surprises. Until I can get in the car and say take me to the supermarket, no we need to stop at the station on the way. There's too much traffic because of the road works, so take med by the backway. even though the snow is covering the white lines. Then automatic cars are not for me.
