Cars don't have to be as complicated and expensive as they are now, especially with electric cars becoming ubiquitous. You don't -need- tesla level electronics and extra grafted on garbage. You need a vehicle that will get you from A to B. I believe that some company will come along (probably Chinese or Indian) that will grok this idea and come up with something that we can fix and they can sell for a profit. Battery tech will only get better and cheaper. I think we can do this :) . The ICE age is coming to an end, but that doesn't mean DIY has to.
