So wouldn't a driver knowledgable of the city streets that you don't ever have to give directions to be better?
I use Uber all the time but I find that regular taxi drivers are better in traffic as they tend to know ways around it the GPS doesn't provide. I also regularly get GPS focussed drivers taking 1 turn too early and driving in a circle to get back to where they started to make the correct turn (twice this week already). I still prefer Uber overall but dismissal of street knowledge because GPS is 'better/more accurate' doesn't gel with my experience at all.
Problem solved.
If you give me a clean car, reliability, and a driver who knows the city, I'd gladly get a taxi even if it's maybe 15 to 20% more.
Most of your data points are from a single route (your daily commute) and this may not be representative for all trips, even within your city.
I live in a city with significant variation in traffic patterns from day to day, and GPS with traffic info performs much better than someone who knows the roads.
It's just frustrating to see these drivers driving so distracted (I think they are more distracted before picking up a passanger)
(I reported it multiple times over the years)
But I could do public transit for around 2.50 each way. But adding about 15-20 minutes transit time.
What I really should do is bike to work. It's better for my health, wallet, and environment. I really have no excuse.
I estimate my Ubers this year will work out to around
($20/day for uber * ~60 winter work days) = $1200
Most people with modest vehicles will see a total cost of car ownership costing them somewhere in the $5-10k/year range. So I could double or triple my already heavy reliance on uber and come out ahead.
TLDR: For those with short commutes, a heavily uber-assisted bike commuting plan is a huge financial win. And this is not even considering the downstream value of the productivity and health benefits resulting from regular exercise. Or the value of the time I can now spend reading instead of driving.
If a person is willing to bike to work when it's dry in the morning (even if it might rain on the way home) there's probably only around 20 - 30 days when they'd need Uber, so that'd cut the Uber expenses by 1/3 to 1/2.
The point I was trying to illustrate for anyone reading is that uber is cheap, not expensive, when used to obviate the need for private vehicle ownership.
If you only care about cost in a big city there are likely less expensive options but if time is more valuable to you then cost isn't the big concern.
It would cost $60 - $80 for a one-way Uber trip from San Jose to SF, Caltrain would be around $16/day with a discounted 8-ride ticket, around $10.50 per day if you use a Caltrain monthly pass.
Even if you put 4 passengers in the car, it'd still cost you $35/day for Uber.
I uber to work everyday and 90% of the time the uber driver blindly follows GPS through an alley that isn't really meant for traffic, ignoring the much simpler and faster route that whatever GPS uber uses can't figure out.
But it's cheaper, cleaner, and will show up on demand. But the navigation of the driver is the big positive for cabs.
