I have to laugh at that, my dad does that all the time in his truck. Were were stuck in a drive thru and the lady infront of us would not go park where they told her too (her order was wrong) and we had our food, my dad makes a right hand turn up over the curb and the grass to get out. The boy in the drive thru window was so shocked to see that.
As far as the turning radius I think it turns really well, my boyfriend has an srt4 and it turns around much better than his car, we did circles in a parking lot last night. I thought it was going to be hard to park, we have compact parking at work and I did not have a problem with it.
