Taking a bike when it's 110 F out may be better than walking to a bus stop and then waiting for a bus, but it's still not something that many people want to do...
Bikes are not great. Ebikes might be able to keep up with traffic but not legally. No bike lanes mean your in traffic with posted speeds of 35-40 MPH and actual speeds of 40-48 MPH.
Not to say I disagree with bikes. Ive got all the parts for an ebike just need to mount them. But its not really viable transport around here if you add in the dangers.
If it was an apples to apples comparison then I would rather be driven than drive. But its not.
