I think you will be surprised at the second thoughts you might have at just plowing into the barrier then.
This is a terrible analogy, there is no connection between hitting a speed bump at 10 mph in a 4wd vehicle with suspension designed to drive on a mostly flat surface and hitting a 4 inch bar with a 120lbs robot that is being designed to do exactly that.

This just makes the analogy worse a standard car would clearly never climb a 20" barrier, that isnt what it is designed to do. A 6 or 8 wheel tank steer robot can easily climb over the 4" bar if the driver is smart about it and it the system is designed to do this. There will be a significant number of very good teams who stick with 6 or 8 wheel drive using 6 inch wheels. There will be less people tipping over due to going over the barrier than there were who tipped going up ramps in 2006 or 2010 or up the stairs in 2004. I would even guess that more robots will tip this season trying to go over the bridge than trying to climb the barrier.
