Depending on where you live, Uber/Lyft can be a lot more expensive than a bus.

In Dallas, a monthly public transport pass costs $80. This comes with unlimited uses of the buses and trains for an entire month. Let's say you work twenty days (four weeks) a month, with a trip each way. That amortizes to $2 a trip, less if you also use your pass for personal trips on weekends.

Lyft costs me about $11 on average to get me between home and work. If I were to take Lyft to and from work every day for a month, again assuming twenty working days a month, I'd be paying about $440 a month. That's not $4 more; it's $9 more. That's 5.5 times how much I'd be paying for public transport. Again, that's not counting using it for personal trips on weekends (here, the minimum is $5.70, including the trust & safety fee).

If Uber/Lyft is only $4 more than a bus in SF, then buses are way expensive there.
