Agreed! I work in England 2 or 3 days a week. My commute home back into Wales always puts me on the M4 Westbound around 5pm. The M4 in Newport is hugely undersized but our leaders won't sanction a new road as it does not meet their 'environmental stance' despite spending £150m on designing and buying land for such road before shelving it. For around 10 miles in Newport the traffic is very slow starting and stopping. I will open up a gap between me and the car in front and try find the average speed so I don't have to come to a stop but can crawl along. It's easier on the car, easier on the clutch and certainly easier on my left leg!
Although I miss my old Volvo V40 with an auto box and adaptive cruise. That was perfect for such situations!
I have adaptive cruise and still set it so it doesn't have to adapt much
