NASA & the ESA actively monitors all satellites and actually maintains a database of every little piece of space debris they find (payload fairings, failed satellites, etc). They determine the orbit and track it until it falls back to earth.

Vehicles are tested at a top speed of 80 mph in order to calculate the highway mpg estimates.

EPA utilizes five test cycles to represent real-world driving conditions. While it’s true that the test cycle historically labeled as the “highway” test has a top speed of 60 mph, this test is currently meant to represent driving on lower speed highways as well as rural and suburban driving. EPA’s highway mpg estimates are primarily derived from a separate “high speed” test cycle, which has a top speed of 80 mph. The remaining three tests are designed to simulate stop-and-go city driving, high air conditioning use, and driving in cold temperatures. For more information on the five test cycles and how EPA calculates its mpg estimates, go to epa.gov/fueleconomy.

I would disagree on "having enough infrastructure", after moving to SoCal a few years back. LAX is a complete nightmare. One can easily spend 20-30 mins trying to drive from the airport entrance to the terminal. The horseshoe design cannot handle capacity.

In the past two weeks I've been receiving offers for discounted rides from Lyft. First was 30% off for a week, then yesterday I received a code for 50% off this week. It seems they're trying to inflate their ride numbers quickly. I have not received any promotions prior to this, and I've been a member for over a year.
