Here in Red England, an American flag on your car will probably get you an eyeroll or a nasty look.
A Trump sticker would almost certainly get you costly damage to your vehicle. Perhaps while you are in it!
Shortly after Trump won the nomination I put a Trump sticker on my car. A beat up old Camry pulled up behind me at a red light and the occupants -- 4 or 5 youngish looking guys, mostly if not all white, started screaming obscenities, "F Trump, F you, F you wingnut", etc. Whatever...Until they I realized they were following me. I started cruising randomly, highways and back roads, flicking on my blinker but skipping the turns, etc, and they shadowed my every move, pulling right up to my bumper at stop signs still yelling, all of which I was lucky enough to be able to go through quickly. I avoided red lights because I figured they'd take the opportunity at a long stop to get out and surround my car. I eventually put on a burst of speed on a county road, whipped down someone's driveway and watched the jackasses zoom by, then went the other way.
Reached my destination and scraped that sticker right off. I was carrying at the time so I'm really, really thankful that I was able to avoid a confrontation.
I saw a pickup today,suburban Boston,that had a huge American flag on one side and a huge Confederate on the other side.
Pretty funny.
