I ride an odd bike, a recumbent. I have seen a few cars watching me rather than the road, which is good for me — they give me loads of space — but bad for anyone ahead of me as the drivers show no lane control for a good 50m after they pass me. Where that happened most recently is also where a driver killed a cyclist by wandering into the bike lane despite having a six metre wide lane to themselves (even the cycle lane there is three metres wide)
