Says who? Which expert is saying that?
I have cornered Prius at high speeds and its very very stable, traction control kicked in for a second when I had to turn hard to avoid a bike who came out on the road in the 3rd (high speed) lane at once, hard right almost full steering rotation at once, car was in full control above 90.
Let's put corolla or Prius vs. that museum relic City on a track and see how well they do.
Infact let's ignore the extremist fanboy, Prius has hundreds of patents and awards, all of them are given by real experts, no one cares what an extremist fanboy thinks or bloats.
Oh I forgot, when is Honda going to really launch the super secret back-breaking museum relic old city with antimatter reactors in engine and gravity altering devices to help in cornering? When are they going to stop helping own looters mafia and reveal the price of their flying saucer?
Paddle shifters on CVT (with or without fake shifts) make me laugh.
