Behold The Hyundai Uni Wheel. Transportation May Never Be The Same

This is a most excellent place for technology news and articles.
I worked in automotive for years. Hyundai/Kia fail spectacularly in ways no modern car should. Randomly catching fire to the point you are advised to not park inside, engines destroying themselves due to a manufacturing/design error they lied about, a faulty design in the transmission control unit that causes forward and reverse to invert should there be a short in the tail light, thousands of dollars in damage or engine loss due to a failure of a $0.50 motor that is not weatherproofed, among other things.
After the Theta II engines starting blowing up they came out with their 100k mile warranty. That is not a sign of confidence in their product, that is a confidence-man tactic.
