Fuel price discussion thread (was ‘chaos’)

Filled up yesterday and I also saw a guy trying to fill some kind of container in the boot of his car. When I went to pay the lady behind the till was talking to her colleague and an alarm was going off, wouldn't let him have the fuel, I didn't know they had that kind of system in place. One of them went out and told him to jog on.

Oh and it was just over £2 a litre again for the good stuff. :(

On BMWs, it’s even called “cruise control with brake function”

Nah my van is just a Vauxhall Vivaro not many bells and whistles.

Cruise control only accelerates until speed is met. It has a separate speed limit function which you set a desired speed and with the accelerator hard to the floor it won’t go above the set speed.
None of functions do any kind of breaking.
 
You wouldn’t normally feel the need to cover a Jerry can with a blanket so the chances are it was a fairly inappropriate container.

Remember those filling bin bags and wheely bins during the panic buying phase?

My old car didn’t brake, not even on the speed limiter. My new car does brake but a large proportion of the energy is captured by the electric motor and I’ve not actually seen it use the friction brakes on cruise control.

Erm thats exactly what most do as otherwise you'd be defeating the whole point of cruise control which is to remove speed decisions. People use them as speed limiters. They also aren't doing it to then turn it on and off as the motorway undulates.

What’s most. I’ve not driven a car that brakes if you go over the speed
 
Ours brakes for junctions, traffic etc. It doesn't brake or stop you going over the limit on the normal travel assist(ACC) mode. Have had my best mpg using it. Say if you overtake on the motorway it's will just slowly return to your ACC speed.

Does your M3 have cruise control? If so, it will do this - all new BMW models introduced since the E60 5 Series in 2003 have had cruise control which uses the brakes to control the speed on hills.

Yes. Thinking about it now, the engine braking is pretty high on that engine so it probably never needs the brakes if cruise just lifts off the power.
 
Active cruise control mentioned doesn’t really add anything for speed limit control… other than using the car infront as a reference speed aswell :cry:

in terms of first time market it’s something between S class and XK take claim for that.

Personally I don’t like cruise for the reasons above, back in the insight hypermiling days it was a case of “Drive with load” and drive with buffer. Ie constant throttle and leave enough gap so the car will naturally opens a gap or close to the car in front rather than turning into panic breaker like many drivers do when driving too close.

Correct. I guess I don’t drive down big enough hills. EV make sense as you getting enters back but using brakes to hold 70 down hill seems a massive waste of fuel.

Obviously active cruise brakes when a car is in front but this isn’t what we are talking about.
 
Gone up from 175 to 185 in my local Tesco.

I heard something on the radio yesterday about it possibly stabilising a bit, I hope so, it's starting to go past being a just a bit of a nuisance now.

The speed limit on a Motorway is 70mph unless otherwise signposted and you've set the cruise control to 70mph. So it'll maintain 70mph, either by using more power up a hill or using the brakes down a hill.
