problems getting bodywork repairs done in reasonable time-frames
I don't know much about such things, but I imagine that at 20K units p.a. production run for i-Pace won't have many spare panels floating around the world either.
missing 'modern' features
Tesla has a bucket full of its own of course ... maybe Jag will have all those too ... but entirely depends on your needs as to which are important
Summon (e.g. out of a puddle, or a tight garage), scheduled events (mine include being able to ask Alexa to get the car ready for departure [including warm / cool it / charge it], I can also schedule charging to stop at 90% (overnight) and then resume to 100% an hour or so before departure and put the cabin climate control on 15 minutes before departure. And reset back from 100% to 90% charge limit shortly thereafter. If I forget to do that I automatically get an email, that evening, to remind me.And so on.
Much of that is done with 3rd party stuff, of which there is plenty - I prefer 3rd party phone app to Tesla one, but importantly there is choice. Even to the point of writing your own, if that's appeals to you ... the APP will show me a walking route to wherever my wife parked & abandoned the car ... instead of her having to explain it to me, and allow me to keep an eye on charging whilst I'm having a coffee - in case it tails off dramatically because of an overheating fault on the "pump". That's rare. but blinking annoying when you go back to the car and its only partially charged, when you could have moved it to another pump ... if you had known.
Maybe Jag will have all that stuff ...
... I was impressed with the i-Pace's pushed-forward cabin, making more space inside than the outside would suggest (and I expect good visibility of where the front corners are, when manoeuvring), and all four feet are properly at each corner, which bodes well for the handling, and the silly little "one A4 pad" space under the bonnet on the original marketing video has seemed larger on recent reviews I've seen. Whilst spacious in the back the reviewer's thighs were not "on" the seat (Tesla has that problem too). The pre-heating of incoming air, using heat-pump, is a good idea too, and should help Range in Winter (i.e. warming the battery more quickly, and with less energy, although of course when properly cold the COP of a heat pump teds towards being the same as resistance heating, but "Good in UK" I reckon). Likely that i-Pace regen is stronger than Tesla too. More reviews, in particular from somewhat longer, on-road, journalist-reviews will shed more light, and answer some of my questions too: What's the actual real-world range? Rapid charge taper? A/C Charging has disappointing low max-limit.. Will its "stay in lane" be equivalent to AP on the motorway (which is pretty much all I use AP for). Battery degradation will have to wait for a long term test of course, but if Jag give as generous a warranty on that, as Tesla do, then not the owner's problem
Personally I'm not mad about all the knobs on the dash. Very familiar to existing car drivers though ... but having had Tesla for 2 years I've become very comfortable with minimalist and button-less-dash, and no door pockets accumulating old rags and Coke cans ... Quite likely that voice recognition will upgrade (i.e. on the current model I own) to the point where I won't be pushing any buttons. Long gone are the days when I learnt to drive and my Father expected me to be able to select any function without taking my eyes of the road. Those 4-button-presets on the Radio made that easy, but who today wants only 4-station-music?
, so either loads-of-buttons, or voice-control, are the current contenders for control of a complex dashboard, and minimalist is the better starting point for voice-control.
Before you make you mind up I recommend you talk Tesla into lending you one for the weekend, so you can try all those features yourself. I don't think they normally set up Phone APP for loaners, but I expect they will if you ask (Journalists have had that made available to them).
