I rented a Nissan that would scream at you for deviating from a lane. I couldn't turn it off fast enough. Driving on a small winding road was constant false positives. Even on the highways, faded and repainted lines was throwing false positives. It was more of a distraction than a help. When driving in an unfamiliar city I didn't need the car distracting me with its disfunction.
Turning it off was buried deep in a menu that was not convenient to find. There would be no way to quickly or safely toggle it on and off as conditions vary.
If you can grow some of the smaller varieties at home you might like them better. The bigger the melon, the more diluted the flavor seems to be.
