I hadn't shopped for a new car in over 10 years so yah that's probably dead, they probably figured out some really good glue and got rid of enough body flex. Still it looks odd to me, just a bare windshield laid on bare metal. It looks "unfinished" to me, with nothing covering the "seam".
Nope, at least not until that "seam" starts filling up with random shit like pine needles, road debris, dirt etc. Even hitting it dead-on with a hose can't get some of that stuff out. Usually wind up shoving a zip-tie in there to get it out. Been tempted to fill it but I'd probably f it up.
Yeah, keeping it clean is a good idea. I washed my fiance's grandmothers car a few weeks ago, her rear window is like ours(and the windshield) all kinds of dirt/grime/pollen/mildew came out of there. UGH. But if it doesn't get bad, it should never be a problem. If you never wash your car with a eye for detail, it'll probably get gross.
