BPT is right on the money.
Most drivers are idiots in first place. If they are texting or yakking incessantly on a phone while driving then triple the idiocy.
Last night I was coming down 70 and CDOT was doing work in the left lane of the eastbound tunnel just east of Idaho Springs. Everything was well marked at least 2 miles before the tunnel, approaching the tunnel there were 3 police cars. What do people do, they stay in the left lane until the last possible nanosecond and then cut in front of the guy to their immediate right. I had some jackass in a big box truck try it on me, he ended up cutting the guy off behind me.
Those cops could have made a fortune writing tickets for careless or impeding or something, I don't know traffic law.
The rule that most folks follow when driving goes like this - "you're first, right after me, and if I cut you off well tough shit, I'm first".
