All automotive innovation is around self-driving and autonomous-rich cars, all of which have electric, not fuel, powertrains. If in five years time, the top models from the major marques & the cars from Tesla, Google and Apple are all electrical, the impact will be felt by octane suppliers.
Most drivers who try electric vehicles will not return to gas
. This is my experience too, having driven a BMW i3 a few times. Driving electric just feels so much more sensible. Apply the pedal to get power, take it off to slow down, minimal use of the brake; and sublime access to instant power. Do try electric if you haven’t.
