It's primarily for air-cooled motorcycles, and to prevent them from overheating = no airflow = no cooling. Although ill tell you this, as someone who rides a motorcycle in the only state in the US where its lawful. Ive seen people get rear ended on bikes because the person behind them was not paying attention (or did not see them, which can also happen, motorcycles blend in with tail lights). I've seen this happen at stop lights, and in stop n go traffic on the motorway. On the motorway the man was wedged in between two cars and his face was stuck in the trunk of the car in front of him, with the car behind pinning the bike down. Oh man i think at stoplights is worse, this guy was pushed into the street into cross sectional traffic. Even when I drive on the highway and am NOT lane-splitting people move over to the left (fast lane) to offer more space for me to get through if i wanted to be. More states should allow lane splitting, it allows the rider to lawfully put themselves in to a position where they are less likely to get squished, but also contributes to less traffic due to having smaller more efficient vehicles on the road. Uber you should get a bike.
