I watched the video. The description over on Autoblog is accurate:

The numbers we can see show what looks like some tenderfoot driving. Keeping in mind that the speed limit for Class 8 trucks is 55 mph in California, the Semi did 55 or below for the opening stint; at one point doing 29 mph on what looks like open highway. The driver follows another rig on I-5 at about 60 to 65 mph for a spell, up to about the one-third mark in the trip. Then he locks into 55 or 57 mph for the long stint through central California, dropping as low as 44 mph and 39 mph for a surprising length of time.
For the final 100-mile stretch from Riverside to San Diego, after the driver takes his mandatory break, he doesn’t exceed 51 mph in the video, dropping as low as 47 mph on open highway.

Average speed has to be less than 55 mph. (Which is likely why Tesla did not release the full uncut video like Musk said they would from the stage - it would be easy to calculate the actual moving average)
Congrats to Tesla for delivering their first Semis but it is hard to claim a 500 mile range when the truck is going under the lowest truck speed limit in the USA.

That would make it 1,000 lbs lighter than the dry weight of a Freightliner Cascadia day cab. That isn't likely considering the 1,000 kWh battery. (Musk said it averaged 1.7 kWh / mile on that run so with a 10% battery buffer it would be 1005 kWh)
Some educated guesses are putting the Tesla Semi 300 at about 25,000 lbs +/-
Musk being Musk also had to throw out some crazy sale projections. He said Tesla will sell 50,000 Semis in 2024. For reference that is about 25% market share for Class 8 trucks in the USA. So considering volume production is expected to start until mid-2023 that is 0 to 25% in 18 months.
