Car covers a pain to take off and on.If you have one on in a airport It will draw unwanted attention to your car.
That is a good point, thought about it, but that is why I have insurance. Attention is OK, but vandalism or theft is another and not good; not sure a thief will be more or less likely to want to bother with it. It is for weather only not security. I read some where VW was not high on the to steal list. The pros get a shopping list and target cars. For some reason a 1995 Honda Civic is #1 most stolen. For the casual joy riding kids I think the risk is lower.
A good topic, how to keep your car from getting stolen. If they are looking for a TDI Sportwagen they are going to take it (or try) cover or not. To avoid attention from a car cover, the color should be ugly, a dull finish, may be beige, light brown or faded green, no bright blue.
It's parked in a semi secure, attended, not for public, parking lot..... Also tucked into rows of cars it is also somewhat hidden; plus there are a few other car covers. I agree they are a pain but feel better knowing it's not sitting out in direct sun, 5 days at a time..... You are probably right, I'll get tired of it and stop using it; that is OK. Putting it on or taking it off in rain, wind and sleet would not be fun.
