People have had issues with Ather side stand sensor. A workaround was to place a magnet near the sensor (or something, I don’t exactly remember) and continue riding, even if it shows side stand is down. As soon as you stop, it would turn the scooter off.
If they implement it as you say, then having a broken sensor is as good as having a bricked scooter
Will try and search for a source of my workaround but it was a while ago, when researching for purchase
Edit: either way, this was discussed before here
A more useful function would be to restart scooter when killswitch is engaged and disengaged when riding. So that accidental killswitch doesn’t require to completely stop and again start
