Not to have a go at them, because they're just doing a job, but my god do lorries get on my tits. The other morning I pulled up behind a lorry going slow (virtually stopped) on a hill and thought there isn't normally traffic at this time in the morning, just slowed down and because he was barely moving I put my handbrake on. Anyway turns out there was no traffic at all, it literally took him 2-3 minutes to get up a hill which would normally take 20 seconds. And of course he went the exact same way I was going. Just pure impatience on my side, but still irritating.
