Driving is dangerous business. We tend to forget since it’s so commonplace and integral to our lives. Cars have gotten much safer though, no longer the top cause of TBI in the US

The cause was tractors stopping all traffic on a highway, setting up show with barbecues and what not. Then some people drove into the tail of the traffic jam.

Has nothing to do with driving being dangerous, but with the choices of these farmers to start a demonstration in the middle of a highway

They already did it a few times before, and they were warned that they should expect killing people. The question was not if, but when. They still did it.
