I've recently purchases a manual transmission 1.5 Honda Mobilio. Which claimed to be a drive by wire vehicle and I assume it really is (don't know how to tell if a car is drive by wire). I am a new driver and on my observation, when I take the key out, the steering is ultra hard to turn at all compared to me turning the key to II or ON.
The user manual also says, steering may be disabled when car is off or hard to control when the car is off, warning me about free wheeling down a hill with the car off.
My question is: Is the main reason for the disabled steering the drive-by-wire system or is it because of the power steering system not present when off?
