Not aimed at you in particular either, but road crews in general (including tow truck operators, other emergency services etc.)... this is a shared responsibility... please don't be lazy putting out safety devices.
I write this as an ex tow truck operator and ex EMT. I can't count how many times I have had to jam on brakes or have had traffic snarled because someone couldn't walk back the proper distance for the road speed (at least 100 metres) and put out a cone or a lane closure sign to give drivers advanced warning.
The one day, a guy was unloading equipment in a 60 KM zone in the inside lane with *ONE* cone about 1 metre from his truck. People weren't noticing that he was stopped and just about hitting him... he even looked nervous, but didn't even seem to consider putting the cone (or more than one, what a concept) further back. The truck in front of me did a california lane change at the last second, leaving me doing 60KPH mere feet from his truck. Luckily, I have good reflexes and brakes and I'm not scared to use them, but I do think the back tires came off the pavement.
That's just one recent example, but it's pretty common.
Anyhoo, like I said, you guys probably aren't in that category and yeah, drivers are pretty "me me me me me" stupidified... lately, I swear they opened an insane asylum, let everyone out and handed out auto keys at the door.
Let's all work together to not kill peoples dads, moms, husbands, wives etc. that are doing US a SERVICE, K?
