Is this correct?

Stuff reports:

Wellington road policing manager Inspector Pete Baird said most buses trundled along the Golden Mile at between 13kmh and 17kmh but getting hit by a 12-tonne bus “is like getting hit by a car at 140kmh”.

Is it? Instinctively I’d choose a bus at 17 km/hr over a car at 140 km/hr? I’ve been run over by a bus, but never hit by one, so I can’t judge off experience.

Someone with a better memory of physics want to calculate the force in each case?

Incidentally the article is on lowering the speed limit in the golden mile from 30 km/hr to 20 km/hr, which I’m fine with.
