tricks to blending in

I have always owned vehicles that seem no different from 98% of the others on the roads. What have you done to stay "invisible" in either your daily commutes (beyond the obvious: staying in a pack and keeping to the speed limit + 5%) or on country-wide tours (the decision to take back roads vs. freeways, which ultimately comes down to "I'll get there when I get there" vs. "OMG, I am late for a meeting")? I am contemplating driving, not flying, from the midwest to the east coast in March (barring crazy weather). Any advice when staying at hotels, choosing parking garages beyond relying on "your sixth sense"? Use the car cover overnight? Park in an isolated section? Just trying to minimize risk and take sensible precautions (that I never had to think about until now). One's response could be, "**** happens - that is why you have insurance". But I guess I am looking for practical advice [ELI5] that could be baked into various decision-making moments.
