I’ve had plans to convert whatever car I have for like 15 years–and yes I’ve done my research, my friend helped me and he has a doctorates in electrical engineering so it’s more involved. I have a Jeep wrangler for that reason. The potential solutions for conversion are crazy now. At this point it’s cost. So the counter to your statement, if you manually convert you end up with a RC car instead of a surveillance system. Tech has advanced so fast that, you can ask why did I hesitate? Because of simple things like using lead acid batteries got quickly overtaken by lithium variations. Hybrid combinations are solutions as well. And heh… I’ll give you a kek for the $5 a gallon, it’s a bit more than that now.
