Hi Chris,
Welcome to the fold, although it looks like you've pole vaulted right over the top of me in a single bound with the Tesla and solar panels.
You might have seen I've recently gone from the Peugeot Ion to a 2016 30kWh Leaf - a modest car compared to a Model 3 or even the e-Niro but a nice step up for me. I really like the car, a lot more than I expected to even though I'm an experienced EV driver by now and sort of knew what to expect... it's super smooth and quiet compared to the Ion, although at 80kW / 107HP it doesn't keep up with the Xantia above 50mph let alone a Tesla.... nippy up to about 50mph then fairly flat but adequate above that. But I didn't buy it to be a speed demon.
Interesting to see your comments on the comfort of the Model 3 seats - the seats have gone through several iterations in the Model 3 since launch in 2017, and I think they have improved quite a bit in that time. They do look comfortable. I've always been worried about the "firm" ride people report in the Model 3 so it's good to hear that the seats can make up for that to some degree.
The drivers seat is the one thing that has disappointed me a bit in the Leaf - I don't find it very comfortable and I'm having to mess around with cushions/covers to try to find something to make it a bit more comfortable for me....and I haven't hit on the right mix yet. The full leather electric seats in the Xantia are much more comfortable and adjustable.
The ride on the Leaf is soft but has very limited travel, probably like a lot of modern cars and I suspect the Tesla is similar. Small bumps are taken very well (better than the Xantia) with good isolation and an overall "cushioned" feeling, however larger bumps hit hard and cause the car to pitch and kick due to inadequate suspension travel. The Xantia is slightly harsher on the very small bumps as Hydractive 2 tends to be, but swallows up the larger bumps that cause the Leaf to pitch as if they weren't even there, and the Xantia has that super stable unruffled feeling over undulating roads that I haven't felt from any conventionally sprung car to date.
Although I can't afford either until they get much older, I think for me beyond the Leaf my ideal EV would be a toss up between the Model 3 and the Kia e-Niro. Strange to put them in the same sentence on first glance but they share a lot in common especially range.
I like the Model 3 a lot but I do have some reservations about it. The Sedan boot is the main complaint I have with it - and I see this has been addressed by the Model Y which is back to a hatchback again like the Model S and X. Really odd choice to go Sedan IMHO, (probably due to the glass roof design) and while it's quite deep and roomy it's just not as versatile as a hatchback.
I also have a love hate relationship with the centre console on the Model 3 - the functionality it provides is absolutely outstanding and class leading, but..... I find the rest of the controls (or lack of them) too minimalist for my tastes, including the lack of heads up display. Would it stop me buying one ? No, but I like my buttons and switches and other tactile controls in addition to a top notch central touch screen. The Model S had both the centre console and a normal heads up display with controls, and I think I prefer that arrangement.
Lack of a heat pump in the Model 3 is a little disappointing - I see that they've included a heat pump in the Model Y for the first time.
How do you find the door handles on the outside and the door release button on the inside ? Do you have to explain to every passenger how to get in and out of the car properly ?
A major selling point for Tesla's apart from their looks and crazy performance is the supercharging network - that alone can tip the balance from another model of EV. The public charging network isn't too bad in Scotland (I'm in the central belt in Lanarkshire) but in England it's pants with a mishmash of networks.... so doing long distance journeys without access to the supercharger network would not be fun at the moment even in a longer range EV.
In regards to "Going green", while I'm sure many people buy EV's with that intention, it's also OK to just like the driving experience of an EV in its own right and buy one because of that.

It's one of those things that until you've lived with an EV for a while you don't "get it", and a lot of drivers who have never spent time living with an EV have a strange view of what driving an EV might be like, as if it was somehow like driving an oversized golf cart.
There is something very enjoyable and relaxing about driving EV's - especially those with higher performance. They can still be fun without the "noise and fuss" of a combustion engine, but fun in a different way. It's also OK to like both.
I still enjoy driving the Xantia V6 as well and enjoy going back and forth between the Xantia and the Leaf - they both have their strengths and weaknesses and complement each other well. But when it comes to day-to-day getting to work and back the Leaf is the clear winner as it's just so smooth, easy and fuss free to drive especially in stop start traffic, and so cheap to run. It's nice to be able to sit in the car with the A/C running while waiting for SWMBO without leaving an engine running the whole time... preheating/cooling via the app is great etc... and I don't miss going to petrol stations!
Although I haven't owned the Leaf through an icy winter yet I am looking forward to timed, plugged in preheating to melt the ice for me automatically in the morning - although I did use the heater in the Ion to melt the ice it was a manual process of turning the car on and locking the car with the spare key while the heater ran... proper preheating is fuss free.
I think you might be the first Tesla owner on frenchcarforum ?
Interesting your comment on the effect of very wet roads on the range - I see quite a big drop in efficiency (and therefore range) on the Leaf when there is standing water on the road and heavy rain - much more than I remember for the Peugeot Ion, however that may be because the Leaf has much wider 215/50/17 tyres vs 145/65/15 and 175/55/15 on the Ion. Who knew that pumping water off the road used so much energy.
