New tacho rules in Europe

I’m just sat at the BE/NL border watching the constant line of truck flying in and back out again. I’m talking 100’s in an hour not 10’s. Despite the numerous near misses in the rest area, the near constant line of trucks rejoining the motorway is not going to be long before it goes spectacularly wrong.
Obviously they didn’t have their green hat on when they dreamt this one up either as hundreds of trucks an hour stopping then getting up to motorway speed again all in the same place is hardly going to help the eco drive even if they all ■■■■ strawberries out of their exhaust.
I’m sure someone far more qualified than me would be able to put a carbon amount on it?
