Take a look at comma.ai and openpilot to see whether your car is compatible. I’ve put about 100k miles on my comma running on my Honda Civic. Then you get a working car that’s not a deathtrap and improved self driving features.

I ended up falling into using a surface for my travel and it’s been surprisingly good. I have surface pro 7+, and it’s small enough to use on an airplane seat, has good battery life, a great screen, and can do some limited gaming. With an upgraded drive (1TB for $100) for movies and low end games it’s a great little computer. They also run for 200-400 dollars on eBay.

I think it’s simple enough without even using analogies to explain. The unit Watt is Joules per second. Multiply by units of time and you get the total units of energy in Joules. Watt and Watt Hour are just that with without the additional units showing or being simplified.
