I'm a new owner of a P3D "stealth" model in the UK. Was originally getting the LR AWD but was offered the old spec performance model for same price in the end to clear out some existing inventory. Having had little experience with the car so far, and in support of the original post, I personally find the car much nicer to drive for most of the time on most of our UK roads in Chill mode rather than Sport. Even in Chill, I can easily leave other traffic for dead at the lights, and it just seems to make for a more relaxing driving experience all round and should also be getting better range and helping the environment (that is why you bought a Tesla right
Of course there are times when I want to use the full power, and I'm sure as I get more confident in the vehicle this will also help, but to all of you macho types out there I have to say, choice is good! One of the really great features of a car like the Tesla M3 is I can change how it drives and feels from the steering response to the throttle to the creep mode, all with just a few screen presses.
I have owned a couple of electric cars previously and neither had anything like the same level of customisation. Previously switching to eco mode in cars like a Renault Zoe was like turning it into a milk float that could barely move up steep hills, so there really was only one driving mode option that was usable in my view.
I would add to the original poster's wish list, in addition to having "standard" mode sitting between Chill and Sport, I would like the option to have a shortcut on the front screen to swap between driving modes rather than need to dig through the menus while on the move if you want to change. At least on the old Zoe there was a mechanical button allowing you to flick between range saving eco mode and normal driving on the fly. I quite miss that.
I think even for folk that don't want this option on their screen, it would be a great feature if we could choose as individuals, our own menu options to shortcut to a corner of the screen or at least to a section of the quick access menu, rather than just the ones dictated by the software developers.
