   He was right. Reving to high speeds to slow down can quickly damage your   
   engine. That should not be general practice if you care about your   
   vehicle. If your brakes fail on a steep hill, OK. But doing that rather   
   than keeping your speed below the over-rev point going down hills is   
   just stupid. Use your brakes for exiting the freeway, definitely better   
   than over-reving.
