Theory: drivers in utes and SUVs are less likely than regular cars to give the thank you gesture if you let them through on a narrow road, even accounting for the frequency of each vehicle type on the road. Does this hold out for you?
I drive an SUV and always to the thank you wave. Sometimes twice, once out the side window for letting me in, and again in the rear view just in case the first one wasn't noticed
This is true. I posted that comment because it's getting hard not to associate those cars with bullying behaviour even though I know there's very legitimate uses for those vehicles.
