Sure, nobody likes mowing the lawn, and to be able to get the chore over with faster would be great. But a riding lawnmower that can get up to 96MPH seems like it might be a bit of overkill.
Bobby Cleveland created this monster because, well, he wanted to. Sure, you'd need to have a lawn the size of a football field in order to get it up to speed, but nobody says you have to gun it every time. Even running it at a downright-reasonable 30MPH would probably get the job done a lot faster. Just make sure you don't run over any rocks or anything! That could be a disaster.
