The car falls back to its own default mode at every start. With "Set at
start" (on by default), the service sets the mode last chosen on
Settings and confirmed by the car again, once, while the car is in P at
0 km/h, and gives up as soon as the car leaves P or after two minutes
(DriveModeWrite.atStart, unit-tested). The buttons and the start share
the write and read-back (DriveModeSetter). Not tried on the car.

The owner lifted the read-only rule for the drive mode alone. Settings
has Eco, Normal, Sport, Snow and Custom; the lit button is what the car
reports. A tap reads gear and speed fresh and writes only in P at 0 km/h
(DriveModeWrite, unit-tested; unreadable is a refusal), through a CPM-only
write behind EVHardware's standstill gate, then reads the mode back and
says what the car reports. The wide layout's charging price joined the
battery card so the page still fits. Not tried on the car.
