I would definitely let my wife drive if she wanted to... She is just not comfortable with the size of the vehicle. (She has a tendency to scrape the vendors and wheels of our other vehicles.) she hasn't driven it... Yet.
My wife drove it once about a year ago. Said she loved it, but has not asked a single time since then (not that she has to ask, but you know what I mean). I'm pretty sure it's out of spousal respect cuz' it's my toy, or perhaps it's the fact that she has damaged both front and back bumpers of every car she's owned over the last 15 years. Either way, I'm just sayin'...
My husband had never driven my Karma, he is scared of it. I think he had only ridden in it 4 times in the 14 months that I have owned it. It is my daily drive when weather is nice, my bad weather vehicle is a H2 Hummer. He drives it some. He is considering getting a Volt or something green to run around town in since I am averaging 403 mpg - He is very impressed by it.
Wife loves to drive it but a little wary of the width of it (the car not me). She scraped the rims a couple of months ago while parking. I did a silent smoke.
Had them repaired for $75.00 per rim--took about 2 hours for the whole job and the guy did it in my garage.
There's a solution for everything.
