I believe they also get indicators on their steering wheels - not just the blue flags/lights on the side of the track.I can absolutely see an argument, but Msrtin forgets that these cars are stupidly hard to see out of.
I reckon you need to start giving penalties earlier though
Agree though that they need to start handing out penalties like chocolates at Halloween - the backmarkers would soon get the message. Mind you, what penalty can you hand out that is meaningful to a driver who's not going to be in the points anyway?
