Not sure if the MG 4 is the same as the ZS EV, but I have noticed on both Gen1 and Gen2 it is possible to be applying pressure with your foot ( if incorrectly sited ) to both the “Go” pedal and the “Stop” pedal at the same time, if that makes sense.
If you have large feet and a wide sole on the sole of your shoe, when you start depressing the brake pedal, and tend to favour the right side of the brake pedal with your foot, as the foot brake sinks, the right side of the sole of your right foot, can come into contact with the “ Go” pedal at the same travel point.
As the foot brakes travel increases and reaches the point where it starts to become affective, the right side of the sole of your shoe comes into contact with the “Go” pedal.
At this point, the sole of your shoe / foot has contacted and bridged both pedals !.
You can experience an odd feeling of the car accelerating when you feel you are actually trying to use the foot brake in order to slow down ??.
It can feel a bit disconcerting when it actually happens.
The point at where the foot brake starts to slow he progress of the car, is at the same foot level, of “Go” pedal point of kicking in.
I have experienced this a few times TBH.
