Mostly because they say things like "bike lanes make car congestion worse", when the evidence is generally that bike lanes improve car transit times. Or claim they don't want bike lanes because cyclists break the law all the time, while not noticing how motorists break the law even more often - in a multi-ton vehicle - nor realizing how much infrastructure has had to be put into place to physically prevent motorists from breaking the law even more often. Or claim they don't want their tax dollars to support rich people in lycra, while they simply don't see the poor people who use a bike to get around. Or say they need a car to transport the kids around to sports events or band practice, when their 13 year old could cycle in their own should a real bike system exist. Bike lanes can even offer an alternative routing that an ambulance can use when a traffic jam blocks the road, because cyclists can pull their bikes to the side far easier than a driver can pull a car to the side. I suspect some of these drivers may like faster medical services when having a heart attack.
