I’d try really hard to get out of the vehicle’s way. I’d go to the right if I’m on the right side of the road, to the left if I’m on the left side—no way me cutting through four lanes of traffic to pull over would help. If I’m in one of the middle lanes, I’d try to get to the closest or easiest side.
(Of course, I’ve been one to pull over my bicycle when they go by… probably overkill)
This reminds me a time when that did happen. I was younger, and my mom was driving me and my sister somewhere. I remember because it left quite an impression on me. We were in the carpool lane, and while it was less full than the others, it was still pretty slow.
An ambulance came onto the highway—I dunno where they needed to get, or if they realized the highway was so congested, but there they were just a bit ahead of us, now stuck because cars were piling up behind them on the ramp, with lights flashing and sirens full blast. (It was loud!)
She immediately started going really slow, only to get a chorus of honks behind her, but was succeeding in creating an open isle in front of her which some people in the adjacent lane used to their own advantage. Everyone in the other two/three lanes—I don’t remember exactly how many—were more concerned with getting ahead of all the other cars than letting the ambulance by. We watched it slowly try to work its way through, and no one was letting it through, it was only making headway by being extremely aggressive, and cutting in front of cars trying to cut it off. (It still had its lights and siren on, mind you).
They finally got to our lane, which had a long stretch of clear road by now, did that hand-up-and-nod thing, and sped down the stretch… and I dunno what happened after that.
It was insane to witness, and I wish I was exaggerating.
