Nah that's because that's because it's an easy label. Every other time you get tailgated by a dickbag, you probably look back, don't see P plates so it doesn't store there, and just shrug it off as another dickbag.
Much like when you look at the clock and see "OMG 9:11, I always keep looking at the clock when it's this time, freaky"! When in reality you've checked the time plenty of times during the day, yet the other numbers aren't significant enough to make a connection.
Imo .
Also could be many p platers drive like douchebags. But that doesn't end when they're full license... they still drive like douchebags *shrug*
