Like a kid, "stranger-danger" in that getting into a car with someone you don't know. It's like Russian Roulette - yeah, five out the six chambers are empty, but there is that one. So, if you would not play Russian Roulette, I'd suggest not getting into the car either.
Construction guys are not all that bad, they have an image to live up to, and like it or not, for every women who feels objectified there is one who enjoys it. For the most part its harmless. We do it all the time at work, and there are women who don't like it, I know that and I almost feel bad, but there are all these women who are dressed to the nines for the Big Show, and they did that to get noticed. So it goes.
