This is crazy you could never make any vehicle have this kinda steering layout. You would imagine that it would be horribly unstable at high speeds +30 km/h. I can't see this being a good idea but it seems to work.
There's a reason why 100% of street vehicles have front steering. So how tricky is it to drive such a trike? Could I take a normal trike and flip some stuff 180 degrees and have the same results?
