Start-stop, a good or bad feature of modern vehicles?

[Matthew]

I've turned mine off, it hasn't done my battery any good, first time in 20 years I've replaced a car battery.

it's the first thing I turn off when I start the car up.

I believe the featue is in cars to (and this is by no means exhaustive);

• increase fuel efficiency
• reduce emissions
• noise reduction
• less engine wear when idling
• cost savings if the above are true

That said, the disadvantages appear to be (again, there may be others that should be in this list);

• battery wear
• start wear]
• delay in responsiveness
• imapct on your driving exoerience as it can be inconvenient / annoying
• limited benefits depending on your driving habits, conditions or style
• increased maintenance cost

Personally, I feel the disatvanges for me outweigh the advantages, so off it goes. Racing the old lady in the Citroen C2 off the lights when she doesn't know we are racing is less fun when I have to wait that extra moment for the car to start up!

My battery is usually below the threshold for it to activate. I would use it but if it got annoying it would get turned off.
Keeping the footbrake on is a pain for those behind, should only be kept on if at back of a queue then just use the handbrake once someone is behind you.
