I did not even think of return. I am thinking if it is helpful to do a test drive rather than driving the car right after delivery. I little test drive will not make me used to the new things so not sure if that will help.
Let me put the question differently, if you were to drive the Tesla for the first time after the contactless delivery, would you have reached home easily? Especially if you have years of driving on diesel.
If the question is, will I be able to drive this car safely home, or is it too different, yes you will be able to get home safely, BUT I would recommend a couple of changes to the settings to make it more like a "regular car" to get home.
(Note: All recommendations are "for the drive home in my new car" and are not ment to imply you should leave it that way. These settings will get you closer to mimicing a regular ICE vehicle, but consider changing them after you get used to the car, however long that takes... probably a couple days)
1. Turn on Chill mode acceleration, because the car will accelerate a lot more quickly than you are used to. Turning this one turns down the amount of acceleration the car will make with pressing the pedal, so will feel more like you are used to.
Settings (car icon on bottom of screen) --Driving --Acceleration -- Change to CHILL
2. Turn Steering mode to Comfort (optional). If the car you are coming from has "soft / loose steering", turning steering mode to comfort introduces a bit more feeling of play into the steering (making it more like you might be used to).
Settings --Driving --Comfort (will default to standard I believe)
3.Turn regenerative braking to low. Regen braking can be a bit disconcerting to new owners, until they get used to the feel. I dont think you would have much problem with this, as long as you think of it like "downshifting to a lower gear on my motorcycle or manual transmission car". If you have been driving a "stick" then you can likely leave this on standard. If you havent, set to low for your drive home.
Settings -- Driving -- Regenerative braking -- set to low (recommended if you are used to automatic transmission, optional if you are used to manual transmission)
4. Set stopping mode to creep - "Creep" as a stopping mode will allow the car to roll forward when you take your foot off the brake, just like an ICE car. Normal settings of "roll" mean you have to put your foot on the accelerator to move the car, vs taking foot off the brake for the car to inch forward. I highly recommend changing this to creep for your drive home, to feel more "normal" to you. This is one you can consider what works best for you after you get used to it, but for new owners I recommend creep mode because it will feel familiar
Settings -- Driving mode -- Creep
Those changes should allow you to feel pretty comfortable driving home.
Now, if the question is , "should I test drive the car to determine if I am comfortable in it, etc. I would recommend it, at least as far as how the seats feel, etc. You have the return policy if you dont like it, and most people do. You get used to the screen as interface pretty quickly in most cases.
Good luck, and pre welcome aboard!
