One of the problems is that a lot of cars have trouble driving at that speed. It's really difficult to get them to remain at a constant speed under 25 mph or so, which can end up being extremely frustrating for the driver and encourages them to go faster than the speed limit. I realize this is a car design problem, but it's still a problem at present until that is fixed.
Is this a European car thing or a driver skill issue? As an American I’ve never had a problem maintaining slow speeds in any vehicle I’ve driven - manual or automatic.
Edit: I am starting to realize that some drivers are startlingly dependent on cruise control to maintain a target speed.
As an American, I sure have. Including my current Prius which doesn't drive consistently between about 5 and 25 mph. And that was true of my previous Honda Civic as well.
Are these newer models or in poor condition or something? I’ve driven well maintained older Prius, Civic, and Accord vehicles without these issues and I LOVED how the Civic handled all around.
2006 Civic traded in for a 2016 Prius. Maybe you're better at handling a car than other people, but my subdivision is 20 mph the whole way through and I have never myself or been behind anyone who can drive that speed consistently. It's always plus or minus 5 mph, usually wavering between them. I don't think all of the dozens of drivers in this large subdivision are bad drivers.
That still sounds like a design problem if it requires skill to just drive consistently at 20 mph. Why should that require skill any more than driving consistently at 30 mph?
You actually think it requires skill to drive at 30 mph? Because I was able to do it pretty well the first time I ever stepped behind the wheel of a car.
Yes I do believe it takes skills to safely hurtle serveral thousand pounds of steel through a neighborhood. You must keep the vehicle between the lines, maintain adequate following distance, look for and follow signs and signals, and have a high reaction time for anything that may cause a potential collision like another car, cyclist, or pedestrian. There is a lot of hand-eye coordination, a knowledge base, and physical capabilities required to drive safely. Driving is a skill. It is something someone learns to do through experience like any other skill.
Yup it is a skill and one that studies show people tend to overestimate their abilities with. All the more reason to invest as a society in alternative transportation and heavily cut down on the overall number of drivers behind the wheel.
Now you are moving the goalposts. We are talking solely about driving at a consistent speed. That is something novices can do without a problem at 30 mph.
I don’t see why it’s a big deal. The streets near me that are 20 mph are all residential streets with stop signs, driveways, and street parking. You’re almost never going a consistent speed for more than couple hundred feet anyway.
This is almost certainly not a European thing. A lot of people here still drive manually and just idling in 1st gear gives you a steady 7-10km/h... or "walking speed" as used in really dense and mostly pedestrian areas cars are still allowed to use. Idling in 3rd gear is around 30km/h (~19mph).
You answered your own question. So I can concentrate on my surroundings rather then having to try to precisely control the speed of a car that's not in TCC lockup.
You don't have to precisely control the speed, just keep it between 0-20mph. Your speed should be dynamic based on what is coming up anyways. Are you just turning on cruise control from the intersection and leaving it until you brake the next time?
I have never even considered using cruise control on anything other than a highway. Am I the one driving wrong?
No, it's just a different style. It's like 1 pedal driving with the brake pedal. It would work particularly well with an electric car where the first part of the brake pedal is regen braking.
Skill issue! I have no problem maintaining low speeds in my car lol. Honestly, for the safety of those around you, please take a driving course so you can safely practice driving at low speeds.
I envy your commitment to saving fuel. I would be on the gas in 2nd so I don't have to faff around changing down when I hit a hill or have to slow down for whatever reason.
