Not sure about the 'net' question so I'll sidestep that one.
Cruise is a basic system. 4 way stalk on the column. Accelerate to any given speed (above iirc 20mph) and pull the lever and it will hold it at that speed.
Each push or pull of the lever raises/reduces the speed by 1mph
Move the lever up or down (like an indicator) or press the brake pedal and it cancels it.
Definitely! Especially when the other car's control is basically the opposite, Mercedes is in the same place but pull forward to set, push back to turn off, move up to increase speed and down to decrease, nothin if not challenging when moving between the two.
