Tried it. Then compared it to the prices that I would actually get using the app and found that they were nowhere close to the estimates on the website, because the website estimate doesn't account for surge pricing, driver multipliers, waiting time fees, or taxes and other levied fees.

In contrast, the taxi service you linked to is the all inclusive price and is generally standard for all taxis as a matter of local law.

In the app, Uber is now more expensive than a taxi in LA for long trips.
