Video: NASCAR drivers deliberately crash into each other in bizarre incident

An unusual incident occurred during a NASCAR race at the New Hampshire Motor Speedway over the weekend, with two drivers seeming to deliberately hit one another.

Tempers flared between Brad Keselowski and Austin Dillon after Dillon drove alongside Keselowski and swerved into his car.

In response, Keselowski banged wheels with Dillon, and the pair both nearly ended up in the grass.

It is unclear what led to the heated moment, though Keselowski later said of the run-in: "We all let our tempers get the best of us."
