I've been in close presence of two Model Y's today, and pass a regular on my trips.
Followed one in queuing traffic, 1 car between, but still enough view to get a pretty good look. It was a blue one, same as our Model 3. I'm not a fan of our blue (wifes car so her choice and we ordered before any in the wild in UK) but Model Y looks pretty good in blue, but that may just have been that it is still clean... Rear view, I liked it. And a nice bit of ground clearance too. Proportionally it looked good and sufficiently different below the bumper not to look like a pregnant Model 3.
Unlike the red one that I saw from the front (apologies to the above poster). Its too similar to a Model 3 not to look like a pregnant version. Not to my taste, but then I feel the same with the Model 3 from some angles.
This kind of echo's some of the early shots of the car. Good from some angles, and not from some others.
Only very few other SUV's look OK from any angle, so Model Y is a step ahead of most of the alternatives.
Slightly OT, but good to see that Tesla have hopefully have learned a few lessons from the Model 3's sill and wheel arch areas. Not sure why the Model 3 didn't have any form of protection there (iirc Model 2 and X do), and the later additions (and free handouts after acknowledging an issue in some areas) are not a proper solution. Admittedly it shouldn't have needed it, but it is a weak spot. Good that Model Y seems to have a more permanent fix.
