Watch as motorist tries to evade road rage driver in Texas

Updated: 

Shocking footage from Texas shows a driver's struggle to evade another motorist with extreme road rage.

The driver of the car with the dashcam can be seen fleeing from the brown saloon, the driver of which appears to have become enraged after a lengthy wait at a junction.

Both cars seem to hit quite high speeds during the short chase, which lasts around 45 seconds and takes place on busy roads.

The saloon tries to block the white car at various points, but fails when the more rational driver dummies to turn right and then carries on, leaving the road rage car trying to block the turn-off.

Once away from danger, the driver settles down to a more sedate pace and simply merges in with the traffic.
