It has probably got more to do with with more of them being bought and 
used. Cars on regular roads are dangerous enough - all terrain vehicles 
are designed for use on poorer quality roads, and more frequent 
accidents are part of the package.

But you've adduced absolutely zero evidence to suggest that this is 
actually a problem. Current statistics report that gasoline powered 
vehicle catch on fire a at considerably higher rate than electric 
vehicles - newspapers report the electrical vehicle fires with more 
enthusiasm, precisely because they are less frequent.
