That would be the easiest thing for the City to do. Just have a machine programmed with the lower rate beside the dedicated spaces, but it certainly wouldn't be fair or make sense. If the dedicated spaces are full and you park your bike 10' away in a regular space, why should you pay 2 - 4 times as much? That puts pressure to crowd the dedicated spaces which could potentially lead to damaged bikes. What about areas where the City has not bothered to provide dedicated spaces. If the regular parking rate is higher downtown than it is on Queen St. in the Beach, why should a motorcycle pay more in the Beach then downtown just because the City hasn't distributed dedicated spaces everywhere paid spaces are located.The only thing that would make sense is to charge a lower rate in the designated areas and a regular car rate outside. But that would just make it more complicated.
The dedicated spaces were a response to scooter parking on the sidewalks. Scooter riders said they parked on the sidewalk because of lack of available space on the street, concerns over damage from cars, and because they were the sames size as e-bikes, which were allowed to park on the sidewalks. Any type of charging, especially full rate charging is going to exacerbate that problem.
