Don't do it....

If you value your legs... 

Hole cr@p ... I never thought of something like this happening.

Good stuff to know ... thanks for posting. 

DH told me years ago to stop putting my feet & calves on the dashboard for this VERY reason! 

When I was able to do that, there were no such animal as airbags. I would drive with my left foot on the dash & use my right to accelerate & brake. Now I couldn't get my leg up that high!
