@Squirelnutkins I think you may have misunderstood my post.
Adaptive cruise control is fantastic in prime driving conditions, but not so much during the morning/evening rush hour (or general heavy traffic conditions). That’s when the driver needs to resume control, and the driver needs to drive to the conditions of the road. For example, if you’re in lane 2 and adaptive cruise control results in leaving a large gap between you and the car in front, there’s a risk that a vehicle in lane 1 will take advantage of that gap in front of you. As a result, your car will now pull back to widen the gap between you and the car that has just pulled in. How does this help the flow of traffic? You’re essentially holding up all the cars behind you. For some this will result in impatience, frustration and risky undertaking manoeuvres. I wonder how many accidents can be attributed to this? If you remove the ambiguity, in heavy traffic conditions, by reducing the space, preventing people pulling in at the last minute, and therefore preventing a domino effect of break lights and potential collisions with those who aren’t focused on the road, then that can only be a good thing.
This should not be confused with tailgating, you can keep a bigger space, and comfortably keep up with the traffic in your lane. The very fact that cars can, and do, undertake to get ahead means that someone is very obviously in the wrong lane. I question the alertness of those who cruise along in lane 2, 3 or 4 - moving correctly, from one lane to another, demonstrates that you are an able, alert and confident driver. Lane hogging tells me the exact opposite!
A good driver is an adaptable driver, one that can look ahead, look out for particular driving styles and assess risk accordingly by preempting the manoeuvres of another driver. That sixth sense comes with driving experience, and whilst driver aids and gadgets are wonderful technological
advances, until all cars are equal then such technology needs to be used appropriately and the driver should always be in ultimate control, particularly when driving in heavy traffic, and adapt their driving style and level of alertness accordingly.
