The worst is Revel, which, in NYC, are ALL teslas/EVs. worst taxi experience of my life was a 1 hr drive to airport in stop and go street light traffic. I appreciated the hustle but deleted the app soon after my gag reflex subsided. they should at least disable regenerative braking or something
By context, he obviously means automatically applied regen breaking upon releasing the accelerator (so-called 1-pedal driving). While its possible to maintain a smooth speed with this feature, some drivers are using it improperly when e.g. approaching slowing traffic by just releasing the pedal and allowing the car to basically brake aggressively rather than feathering it to allow the car to coast smoothly to a stop.
It's likely they mean disabling one pedal driving, so regenerative braking will no longer trigger from letting off the accelerator.
Regen braking is a way of slowing down like drum brakes. It's not inherently any less smooth.
