And this is not an education issue. It's a fact of human nature. If you drive home about the same time every day, and make your left from southbound 1st ave to eastbound A street, you might be very diligent the first 200 hundred times to make sure the bike lane is clear. But by your 1,000th turn some time during your 4th year of making that turn and yet never seeing a cyclist in that bike lane, you're likely to learn to start ignoring it. Two years later some poor guy might be flying down it 20 mph and when you hear him slam into the side of your car after you cut him off, you will swear that you never saw him, and you won't be lying.

It is only reasonable to expect motorists to look where they expect potential conflicts - in vehicular lanes. It is not nearly as reasonable to expect motorists to look where potential conflicts are very unlikely (though still possible) - in a bike lane.
