Utter nonsense in the timescale perhaps, although the amount of EV's the VW/Audi group have planned by then works out at an average of 3 every year roughly. I think the UK's plan is to have every car electric by 2050, a more realistic timescale perhaps.
By 2030, the good old fashioned internal combustion engine will be banned in Germany. I'm sure others will follow suit, and I'm sure the UK will do this too, maybe even before Germany does?
