“Indicating to pass” is insane and needs to stop
On country roads it is a lot less stressful for you and the trucker if you have a cb radio. You don’t need a massive areal and all wired in, just a little handheld for to communicate to a truck in front or behind.
Say you’re towing a caravan at 90kmh. You can just say to the truck behind “white land cruiser and van to linfox truck, I’m slow, in 3km there’s a overtaking area I’ll let you go around.”
Every car in every country should come with a handheld CB radio.
I don’t say this because I want it to help, I say this because I want it to sound like a modern warfare 2 (original) lobby.
