What if I fumble and tap the "End ride" button when locking the doors? Will I lose the car to the next customer with the radar feature on? I get a bit anxious every time even though I know there's a confirmation dialogue preventing that from happening.

Making the "End ride" action require a slide gesture would lessen the worries of accidentally triggering it.

That being said, this is a concept design and I'm sure designers at Bolt have considered this and have their reasons for not using this interaction pattern here. Because a slide gesture is required to unlock the doors when starting a ride and this would run the risk of muddying things too much – slide to unlock or tap to cancel at the start, tap to unlock or slide to end during a ride.
