As EW said, roughly 2.4 - 2.6 feet is the ideal length of an automotive antenna. This would calculate to a 1/4 wavelength of the FM band. The antenna you see is only half of the actual setup though. The vehicle chassis itself is the other half of the setup. Take old rabbit ears for example. There are two "antennas" per say, or two halfs..... but this is actually one antenna setup. Newer vehicles may have the antenna in the glass, but it is routed and zig-zagged around the glass to get this same 1/4 wavelength. You then have the stubby antennas or some glass antennas that are amplified. These also work great, but are OEM. I have never seen an aftermarket amplified antenna come close to touching the reception of a OEM. If you were only listening to local stations, then you would be fine with something like Converted mentioned.
