FedEx reserves 20 Tesla Semi all-electric big rig trucks

Charge rate is variable based on a huge number of factors, not all of which you can see. It also doesn't charge at the full 120kW the whole time.

Some of the factors that can affect it:

- Whether someone is sharing your charger (iirc every two bays share the same backend infrastructure)

- If you are sharing the charger, then who was plugged in first (the second person to plug in will receive lower priority)

- The State of Charge of the battery pack (the closer to the high/low extremes of charge the slower it will charge)

- Temperature of the battery pack

- Condition of the pack

- Whether there are any restrictions on the pack (some packs if they are supercharged a lot will have caps placed on the charge rate)

I imagine with the 'Megacharger' infrastructure given the sheer amount of power needed, they'll have dedicated infrastructure for the entire bay.

Yup, you're also dealing with companies that may have fixed routes and the capital to develop the infrastructure if it makes financial sense.

Your average consumer isn't going to drop $X0,000 to put in a super/mega-charger but a business might.

Try telling a trucker that their truck didn't finish charging because of complicated reasons.
