Stopped pre-conditioning my battery before fast charging and actually saved 15 minutes on a road trip last week

Turns out the car warms the battery plenty just by driving 20 miles to the charger, so I saved the 20 minutes of idle time warming it at home and got the same peak charge rate, has anyone else tested skipping the pre-condition on shorter trips?

Bet my neighbor tried that and ended up stuck at a slow charger for an hour.

Drive 20 miles and you're already at the charger so the battery is barely warm. You only saved time because you got lucky with a warm day or a short wait. Most of us drive less than 5 miles to a fast charger so preconditioning is still worth it.
