Stop-start me if you’ve heard this before...

The theoretical benefits of a stop-start system are not lost on me: reduced consumption, a cut to tailpipe emissions in congested areas. But am I the only one wishing there was a menu option to keep it switched off until you actually wanted it back on? The Jag’s system is not instantaneous on the restart, and does it with a bit of an audible chunter. Other brands, which detect which cylinder is primed for a combustion stroke, provide more seamless operation.
