Another avoid-the-problem-entirely solution is to get a rear rack rather than a roof rack, which attaches to the trunk. These fit sedans, station wagons, and SUVs, and are much easier to put bikes on, as you don't have to lift them as high, nor do you have to remove the front wheel. However, if you have a sedan, access to the trunk will become much more difficult.
That, or sell your car and just bike everywhere.
(What? It's a 2000 foot climb to your favorite trail? No problem! It's just like a 200 foot climb, except it happens ten times. What's that? You want to go seven states away? Bike there! No? Weenie.)
