I wanted to know what the difference those two are?

Drag racing is when to cars side by, side, race from a standing
start in a straight line, usually for a distance if a quarter mile..
The fastest reach speeds of over 300 mph (about 480 kph), and
can cover a quarter mile from a standing stop, in 4.5 seconds..

Drift racing is done by front, or rear drive sports cars, and sport
sedans.. It’s done on courses that can be in a stadium, or a large
parking lot.. The course is marked using pylons (rubber cones), or
other soft objects, and the cars run two at a time, racing each other
through the turn.. They throw the cars into the turns in a manor that
causes them to slide, often side, by side, as in a ballet, while racing..
The drivers are trying to beat each other to the finish, but they are
also judged on the style of the sidewards DRIFTS while turning, with deductions for hitting obstacles..

Please pardon the rudeness of some of these folks.. They they think
it’s a prerequisite for being an F1 fan.. But I can assure you, that people like that are not representative of any real race fan..
