Why would people buy a Toyota Prius and Toyota Yaris when they can buy a better and superior Ford Fiesta?

Even its own name "Yaris" sucks let alone its engine reliability same goes with the Prius

LOL USA cars suck both metaphorically and in fuel economics. Where they do win is the have huge engines and sound great - but reliability is not really a factor. Ford Fiesta is an average car regards its reliability and they cost more everywhere except in the USA.

However that said Tesla might have the answer.

If there ever was a superior Ford Fiesta- which there isn't, since Fiestas are very unreliable- more people might choose them. You chose Fiesta and you love it, warts and all. You also might choose to prove your love by slamming into a brick wall with the intelligence you exhibit here asking the same thing over and over and over. Don't expect that to win over too many drivers to your side.

Ford Fiesta? LMFAO!
