That reminds me of a good, funny film: "Defending Your Life." Albert Brooks is driving his new Porsche, and he bends down to pick something up. Crash! He winds up in Heaven (or wherever). Everyone must watch events from their life and explain/defend them. I also stars Meryl Streep and Rip Torn. Very funny.

It depends on the shape of the round-a-bout (remember we drive on the left side). If 4 roads I treat it the same as a cross intersection. Taking the first road off it is a left turn (left blinker), next off road is the same as going straight through so no blinker, last off road (assuming you are not going back the way you came) is a right turn so right blinker. If you see these blinkers you know where the car is going. Most round-a-bouts are 4 roaders here. If multiple roads off the round-a-bout then it is usually larger so if you see a car going round with a left blinker going what does it tell you that is useful ? It tells you that maybe the driver just forgot to turn his blinker off, or it can mean he turned it on early and is planning on turning off at some stage. You just don't know. Maybe he is going around twice (it happens) so no blinker yet. Personally I wait until it is obvious where the car is going. So blinkers mean nothing and do not help. If blinkers were so important then why aren't they made bigger and more obvious and a standardised shape and position ?
My grandfather never had an accident. He used to drive and treat other road users as if they were lunatics. I try and do the same.

There was a fatal crash on a local highway recently, and two high school students were killed. The driver of a tractor trailer saw a car stopped to make a turn. He hit the car, swerved into the opposite lane, and hit two other cars, killing the students. This is a tragedy, of course, but is there a solution?

The state is going to study the intersection to see if changes are needed. There will be a long, expensive study, but changing the road configuration isn't going to make drivers keep their eyes on the road. From what's been written in the newspaper, the truck driver saw the stopped car too late. If the state recommends leaving the intersection as it is, I'm sure people will complain. I've lived here for over fifty years, and this is the first time I've heard of an accident occurring there. I wonder if the truck driver was texting or otherwise distracted. How else could he not see a car that was stopped in front of him?

In other crash news, a woman across the Hudson River "lost control" of her Tesla and ran into a car coming from the opposite direction - two people hospitalized. I wonder if she lost control or if the car lost control.
