New micro-mobility modes like electric scooters and bike share have changed the way people get around in dozens of cities across the country.

While these new modes of transportation, users are able to travel short distances in more congested metro areas, but there are major safety concerns, including where they are left when riders are done using them.

But a University of Oregon and Cornell University study published March 3rd examining parking behavior found that improperly parked cars – double parking, using "No Parking" and restricted areas, blocking driveways, bike lanes, crosswalks or curb ramps – far outnumbered improperly parked scooters or bikes.

Researchers focused on five cities, including San Francisco and Santa Monica, and found 24.7% of all cars observed were improperly parked, versus 0.8% of all scooter and bikes observed.
