Not too worried until they figure out how to run/fuel planes, freight trains, ships, etc. On electricity or some other BS. What are they going to ship and tow all those electric cars with to the dealerships..electric 18 wheelers?? Electric barges??? lol. World will need oil for fuel for a very very long time. And people are only getting more impatient with there travel/commute times. I would say the future of personal vessels will populate more towards personal aircraft sooner/rather than electric vehicles...jmo. just saying there is more to transportation than just people that want to be more fuel efficient on their daily commutes. If I had to guess, I'd say 80% of people couldn't give 2 shits about fuel efficiency, at least not to the point of choosing an electric ride over something else. Look at how long they have had electric yard tools...people still generally prefer gas powered tools. Mostly because they are more powerful and last longer. Same with vehicles. Back to my original point. Go UWTI!
