Stealth mode
One can achieve 'stealth mode' when they are driving in country lanes or poorly lit areas over speeds of 40mph, and then turning all of their lights off, so that they essentially disappear into the darkness, when you are doing this, you are in stealth mode.

Going into stealth mode is highly illegal, extremely dangerous and foolish, but an incredible adrenaline rush.

Going into stealth mode for more than five seconds is almost certainly going to end in a bad way.

Stealth mode is not advisable for drivers who are not experienced or confident.
