Why only 30?
I think it's technically possible.
I have thought for a long time that fuel efficiency is one of the things that mysteriously doesn't get better like so many other things.
100 MPG, maybe more!
If you want a bigger truck, go to a Tundra. I didn't think that Tacoma had to balloon up so much. I still like it, but I liked how it was a petite truck before. Now, it's not so petite. Nice shape though.
I would like the car to have an auto pilot function.
I would also like it to beep or honk when I drive by women and they are attracted to me.
I would also like the car to have a levitation function so I can just fly in the air when there's a traffic jam. I would like this feature exclusively.
I would also like it to cuddle with me in bed at night, but that's asking too much.
I will settle for these few improvements even if they make no other changes.
