If a bus costs me $2.75, I'm almost certainly not paying $7 for a 20 minute scooter ride. The bus will get me there in ~the same amount of time, 98% of Seattle buses are not crowded, and they don't subject me to the risk of a scooter-car collision, which would quickly be followed by an unprotected head-pavement collision.

Whatever works for you! I'm sure it depends a lot on the part of town you live in. For me, the scooter trip to work is only 10 minutes, while the bus trip - including the walk to the departure stop, the wait for the bus, and the walk from the destination stop - takes more like 25.

If I'm in a hurry, then, the scooter has a clear advantage; it's not competing with the bus, it's competing with Lyft, and it's both cheaper and lots more fun.

Most of the time I use scooters not to commute to work, but to run errands around the neighborhood. Then again the scooter is not competing with the bus - it's competing with my own feet! I do a lot of walking, but it can be really nice to have a motor help you carry the groceries home, or just get you where you're going quickly when time is short.

To each their own! I have a protected bike path all the way from my home to work:
