I was thinking about something like antigravity..So cars can have six degrees of freedom...So no need to take off/land in the conventional sense...I believe movies like Blade Runner and Fifth element featured cars like that. In that case, manual driving will be mostly like sailing a ship. Equipped with a gps, the car can maintain a course. And with a radar with a sufficient range, it can alert incoming bogies so that user can take proper action...
