This cannot possibly be true. I have MANY times gotten uneven suntan (caused primarily by UVA) or even sunburn (primarily UVB) on the side of my body facing a vehicle's windows. Research agrees with this:

Research has found that while the front windshield blocks 94 percent of UVA rays, the driver's side window only blocked 71 percent. To date, multiple studies have shown those that spend much of their time driving have an increased risk of skin cancer and UV-induced skin damage on the side of their body exposed to the sun. This damage is primarily due to the UVA light passing through the driver's side window.
