Does cruise control use more fuel?

may be true in the states because there are no hills and the roads are straight with no corners and roundabouts :rotfl:Problem with having access to internet is that i get asked by many to solve their problems
Well at least i learn something on the way

Correct. Then look at their roads. Mostly flat and with straights many miles long....0 -
My experience.
I've had three cars with CC.
1st a Jaguar Sovereign. CC was excellent with auto transmission and I used it regularly.
2nd a VW Golf (Mk4) 150 diesel GTi manual. An option on what was a company car. Couldn't get on with it after the Jag auto and rarely used it.
3rd a Mazda6 estate diesel manual. Perservered with it as it was standard on the car. Like it. Very useful in speed restrictions on motorways etc. If you want to save fuel set it to, say, 65mph on the motorway and see your mpg soar, not because it is more economical but because it stops your speed drifting up with the rest of the traffic.
Conclusion. Good if you want to drive just under the general speed on motorways etc. You still have to watch around you to make sure that you aren't holding up traffic.0 -

Don't really see the point of having it in this country as the roads are so busy you are continually changing speed to avoid other drivers anyway, so unless you are driving when the roads are very quiet I think it's a waste of time. Having said that, I have driven a lot in the US on very long stretches of deserted roads, now in that situation it was a boon!
I love my CC
I go to work early in the morning with relativly clear roads
so the CC gets set and it stops me going too fast (yes i admit its a temptation on those empty roads)
so helps my economy0 -
It's good to see that you read the complete threadVery good. Thats for single carriageways.This is a system account and does not represent a real person. To contact the Forum Team email forumteam@moneysavingexpert.com0 -

What would you dio !!!!!! if someone was travelling along at 68 mph and you had you cruise control set to 70 then. You could only legally overtake them at 2mph faster than they are travelling
The sections you refer to clearly are interpreted as single carriageway guidelines where you will be on the wrong side of the road overtaking, but i am guessing you probably really do know that when you googled the Highway Code originally

No idea as it is totally hypothetical. I don't have cruise control, but common courtesy would come in to play.sunshinetours wrote: »What would you dio !!!!!! if someone was travelling along at 68 mph and you had you cruise control set to 70 then.
There are 3 choices
1 Reduce your speed and stay behind
2. Accelerate sufficiently to overtake in a timely manner and then pull back in and reduce your speed back to 70 (Get the police, you will be doing 75 for about 15 secs)
3. Really pee the other driver off and sit abreast of him for the next 1/2 mile.
It is always possible to think up situations that can make something unworkable. 2MPH difference means that the car passes in a reasonable time. Literally crawling past is not acceptable and shows that the driver has a total disregard for other road users.
I stand by my assertion that the normal overtaking rules still apply and the motorway ones are amplification. If not what would you do on a dual carriageway? It is neither single carriageway nor motorway.
In the intro to the Highway Code it states that most rules, with very few exceptions, apply to all roads. The official definition being '‘any highway and any other road to which the public has access".This is a system account and does not represent a real person.

You think? At 70mph recommended distance between cars is something like 200 yards - so you'll need 400 yards to make an overtake...at 2mph 400 yards will take you something like 7 minutes - is that "reasonable"?
2 minutes is probably the limit of "reasonable" as far as I can see...so you'll need to be going about 7mph faster for a "reasonable" overtake...
I don't really buy into this, but just shows how numbers stack up..0
