What would you do?

Scenario;

Two lane semi-rural highway posted limit 50 mph heavily traveled.
You are (on a bike) at the end of a group of 5 or 6 cars, you are maintaining 2 - 3 seconds behind the last car. Car following you is about 6 - 10 seconds behind and has been maintaining that gap. There are more cars behind him.

Ahead from the opposing traffic a car is sitting in a left turn lane, you are approaching that intersection.

The question is what defensive action do you take, if any and why?

My choice was #2, I closed to about 1.5 seconds behind the car and did a little weave. The reason was to discourage the left turner from trying to shoot the gap ahead of me, and give him more space behind me. He stayed put and I didn't track him after that.

In this scenario, I would do two things: 1) I would close up a bit (no more than 2 seconds) on the car ahead, and 2) I would move as close to the oncoming lane as practical, to make myself more visible to the vehicle waiting to turn.
I would expect the oncoming vehicle to try to slip thru the gap between the car ahead and the car behind me. I would also be ready for the car ahead to suddenly decide that they need to slow down for some reason!

That gap between you and the car behind you (6-10 seconds) is what the left-turn guy is waiting for. He wants to turn into that gap, because the road is heavily traveled; it's one of the few chances he will get to turn. So assume he is going to go for it, and that he will not see you.

Then what? Dunno. You don't want to brake, and try to "blend in" with the group behind you: too much danger of getting rear ended by them. And you don't want to gas it and close the gap with the car in front of you. You need that 2 - 3 second gap, at a bare minimum. Should you lane spit into the group ahead? Move to the left side of the lane to maximize your distance from the left-turning car? Dunno.

Any of the above - depends on the precise situation. Least likely is to close up on the car ahead.

Yes, much depends on the place, and the circumstance.

In general the drivers in this area are not particularly aggressive.

In this case we were moving at a steady speed, and the intersection had a right-turn lane in my direction. So, the cars in front were reliably (as reliable as it ever gets) going straight. The gaps in the cars ahead varied from very close to 2 or 3 seconds. The terrain is hilly, this was all occurring on an upward slope.

In this particular event, I was able to close up a little for a short distance then open the gap again without being a flow disruption. It would have been different if the car behind was closer. There was a very large gap 2 or 3 cars behind me.

Can you slow, flash your lights and let the car make his turn?

Yes. You will want him on your side as a witness after the car behind you hits you.

Can't see ever doing that unless at a walking pace on a busy street.

I often weave around in the lane or turn on my hi beams if it looks like a car wants to turn in front of me. The eye catches motion and quick lighting changes, making me more noticeable.

This is close to what I do. I move to the left of my lane and turn on my high beams to make sure he sees me, then move to the right of my lane so he gets a side view of me to better judge my approach speed and also to remove the temptation for him to think he only has to clear the left side of the lane if he darts quickly across.

The SMIDSY…

Stands for "Sorry Mate, I Didn't See You"



It's a human-factors problem, an object like a moving motorcycle is not easily seen against a background that isn't changing much, as when the bike is approaching a stationary car. Adding lateral movement greatly increases your visibility in those situations.
The problem applies to cars too, but bigger vehicles have more visual clues for the eye/brain to latch onto.

It's good stuff to keep in your "stay alive" bag of tricks.
