Picture this...... you are travelling at 80km/h down Sukhumvit road behind richard_smith237, then all of a sudden richard_smith237 stops. Yes, I would stop, but most wouldn't.
If you haven't travelled this road, you really shouldn't be commenting, this road takes a lot of traffic, travelling at speeds around 80km/h, mostly faster. Those stupid white lines should be placed on the side roads, coming off the train tracks.
