How sensitive is this to crosswinds on highway/freeway compared to standard Prius or other cars/vans you've driven?
I've had my v since Dec and have yet, so much as to feel a crosswind or turbulance from a passing 18 wheeler. I'd say this is NOT A CONCERN!!
While only having my Prius v/3 for two weeks ran into 30-40 mph cross winds on long trip this past weekend and yes, I did notice making slight adjustments. Even so the car handled very well.
The v is as stable as the Gen II I owned and matches or is better than other cars we have or had including 2000 & 04 4 Runners, and an 09 Rav 4.
