I drive using a combination of electric (battery) and (petrol) sport mode, depending upon the terrain: sport when going up hill because it lightens/eases the pressure on my foot when depressing the pedal. 

 

Perhaps it's because I rarely drive at night that I haven't noticed it before but recently whilst driving before sunrise (no other vehicles on  the road) I noticed that whenever I'm in sports mode and take my foot of the accelerator the rear brake lights come o,  Is this normal? and if so then does it mean that for slowing down the car uses its brakes, rather than the engine easing off on the fuel?

Is this when in some sort of regen mode?

Typo

I believe it is to do with the date of deceleration regardless of whether the brakes are on or not; so regen charging could cause it.

^^^ Nail on head.

PAS did not give their EV's that much slowing that they were required to have Brake Lights come on when you do go to B for more regen.

Actually it is enough to catch out tailgaters or just those driving without due care and attention.  No need to Brake Test them, just lift off the accelerator and move from D to B will be enough.

 

Some manufacturers seem to have gone too far with what ever the Regs are and have Brake lights coming on when there is almost no retarding of speed, 

eg VW Group.

Great idea! Get someone to smash into the back of your new car at every opportunity! 

Only when i know they will not as i am indicating and about to hang a left.

I just use my Windscreen Washers these days and never brake test anyone. 

 

Others discuss it regularly.   

 Reviewers talk about one pedal driving & EV's & ones that do not have it,

and drivers like it yet often have no idea what their brake lights are doing.

Interesting, thank you. 

 

Might explain why, when i'm tired which from leaving home before sunrise (when there is no or hardly any other vehicles on the road) and returning a few hours later (by then lots of vehicles on the road),I find that invariably the car behind me will often either pull back and keep its distance or overtake at the first opporunity whenever i ease off the accelerator pedal. On one occasion recently the car behind got so far back (despite a normal distance behind to begin with) that  I thought they thought I was drunk.
