The "down side" of tiny cars is getting in and out. I rode with a friend in his Prius and popped my back out again.
Since then I have not been able to walk without disabling discomfort.
At least I am back home and can visit the chiropractor who knows my history.
The display panel in the Prius, when the car is turned on says, "Welcome to Prius."
I did not feel welcome crawling in and out of the small car and may never ride in one again.
