I've had a few toyotas and driven many more and with the roadside speed signs they don't seem that far off. I find pretty much all cars over read by about 4kph, give or take a couple, putting the filmer's speed at a bit over 100.
It does seem like the filmer and the one in front are camping in the right lane when they shouldn't be.
I guess I just don't think this is a zinger since this doesn't even register on the scale for me among all the driving craziness I've seen.
