What do you do?
Scenario 1)
- Three lane highway, 100 kph (62.1 mph) limit. Cruise set at 120 kph (74.5 mph). Riding in the Right or Middle lane depending on flow.
- You see traffic in front of you and nobody is in the Left lane. You change lanes into the left lane and cruise past someone doing 118 km/hr (73.3 mph), so naturally it takes about a minute to complete the pass without accelerating.
- While passing, someone doing between 125 kph (77.7 mph) and 130 kph (80.8 mph) arrives behind you. They flash their lights at you and tailgate.
What do you do? Do you accelerate to their speed, even though it may be faster than you want to be driving? Do you continue on your way at the same speed you are driving at, getting back over out of the left lane as soon as it is safe to do so?
First, I would wonder why I didn't check the left lane properly. If you checked the left lane properly you would have seen the car approaching.
If I saw a car approaching I would have planned the pass accordingly instead of being a lazy ass who won't override the cruise control for a brief second.
That's unless he started a passing maneuver at the same time trying to pass you. In that case, maintain speed. If I'm traveling at 74.5, passing someone doing 73.5 in a 62 zone, I'm under no obligation to "pick up the pace" for mister impatient behind me.
Actually, I if I'm at 74 and the person in front of me is 73, I'd just adjust the cruise control and drop it to 73 and maintain lane position instead of making using the left lane to pass.
Summary, unless the road was completely empty, I wouldn't initiate a perform maneuver with only a 1mph difference in speed.
What do you do?
Scenario 2)
- Same thing as scenario 1, except that you have cleared the car you are passing.
- Once clear (e.g. there is more than one car length between you and the car you are merging in front of), you initiate a lane change back to the middle lane, but see that the car behind you is also trying to pass you in the middle lane. You have both initiated the lane change to the middle lane from the left lane at the same time.
What do you do? Do you stay in the left lane and let him pass in the middle? Do you complete the lane change to the middle and let him pass on the left, angry that he had to change lanes twice to pass you, probably requiring that he hit the brakes in order to not rear end you?
If both hit the blinkers at the same time and the other person hasn't started accelerating, I'll change lanes. If they have, then hold position.
What do you do?
Bonus questions: How would your responses to the above scenarios change if the speeds of the travelling cars were reduced by 10 to 15 kph (6.2 to 9.3 mph) on a highway that was still 100kph (62.1 mph) limit?
If I'm using cruise control. I'm using it because flow of traffic is steady and cruise control is set to match the speed of flow of traffic. If flow slows down, cruise slows down. If an oddball is in from driving to slow, then accelerate to pass, the re-engage cruise control.
So no change in response.
