I hope they fix the rain waterfall issue..

Currently in Model 3s opening the trunk causes a cascade of water to the rear glass which then accumulates and flows down fast, past all rubber seals, into the trunk. (It is exacerbated by ceramic coatings that allow a lot of fast water flow and accumulated beads on the trunk)
Hope opening the lift gate in the Y doesn’t flush all the water onto the glass and then have it fall back into the trunk. A wider and more elevated rubber catch would do the trick...

I hadn't heard of that problem. Bjorn did a piece on snow with his X and his 3, and mentioned it was sort of a problem every now and then (roof on X, trunk on 3). I hadn't considered liquid water flow to be problematic though. I hope T makes adjustments with the Y as you mention.

Since the Y is a hatchback, I can't foresee this being a problem on the Y since the slope of the glass higher up int he vehicle isn't as steep. Here's hoping.
