I was blocked by traffic on the outside lane today so couldn't go past someone doing 30 in a 70 for a bit. When I did go past, I was thrown evil looks-I hadn't been tailgaiting.
There's an A road I use a lot, no choice, really, and some drivers are convinced it's a 40 and stick to this rigidly for ages. It's a 60, single lane carriageway. AIBU to want to carry a speed sign with 60 on it? The road isn't signed until a certain point where it reduces to 50.
