My wife used to own a Mercury Sable. I literally dodged a deer with it one day without rolling the vehicle. Ended up in the next lane over in less than half a second still going down the highway.
With my big pickups, I just try to center the deer on my massive grill guard so they don't dent the quarter panels.
I'm with you on this. I recently drove an BMW X5, a 350D M-Sport, and the high level of body roll was a real surprise - straight out of the showroom I turned at a set of lights and thought I was going to roll the bloody thing!
Also, realistically I don't think sitting slightly higher up gives much better visibility.
