So you're saying it's safer to do a 3-point turn while traffic is passing you on either side, than to do a u-turn when traffic is clear???
Ah I get it now. Didn't see where you were making the distinction before.
People can be clueless even when they're doing a u-turn far from an intersection, where it's easier. So doing it close to an intersection isn't inherently unsafe, it just requires more caution.
No, I'm saying that cutting across 4 lanes of traffic is more dangerous, than it is to give people a means to avoid you by making a 3-point turn. You have to leave room for error. Or, as I said, just don't do it. Don't be an arrogant, impatient idiot and go around the block. More often than not this is the far better, safer option.
At intersections your line of sight is more frequently blocked. People turn onto the road and you make a turn? BAM! Right into the side of your vehicle. That's leaving out the possibility that you simply don't see a vehicle, that's going straight through.
With the guy pictured in my video, he obviously makes a habit of it (same vehicle twice, with different accessories showing). Eventually he's going to cause trouble for someone, just because of arrogance and impatience.
