Have You Seen This Car Around Town?

I was walking through a parking lot the other day and I saw this skinny one person vehicle. I'm sure the gas mileage is great BUT how safe is it? I found out it's called the Tango and it is a one person commuter car. What do you think? Would you buy one?

For most commuters, the Tango is the fastest, safest, most practical, time saving, and fun way to get to where you want to be. That may sound like a lot of hype, but studying the various aspects of the Tango, one will find it to be absolutely true.
