Effectively every car would have to drive with their left turn blinker on constantly in order to drive in a regular straight line. Alternatively cars could stage their lane changes which would make them swerve gently back and forth across the road. Since everyone will choose a different strategy, the road would be chaos. People would almost never try to make a right lane change since lanes to the right end sooner. | Effectively every car would have to drive with their left turn blinker on constantly in order to drive in a regular straight line.

The road is four lanes when crossing over I-405, with an additional lane immediately entering on the right from I-405 South, but three of these lanes become exit only lanes in the San Fernando Valley (at Haskell Avenue, Havenhurst Avenue, and Topanga Canyon Blvd) and two in Ventura County (one in Thousand Oaks and one in Ventura), so all through traffic must merge into the two lanes that enter on the left carrying traffic from I-405 North. |
The title text refers to local {{w|magnetic declination}}, the angle between the magnetic north pole and the true (geographic) north pole. This is almost always not aligned with road directions, so lanes following it would slant across the road as in this comic. In addition, magnetic declination varies over time due to {{w|polar wander|polar wandering}}, so the lane markers on the highway would need to be regularly updated. | The title text refers to local {{w|magnetic declination}}, the angle between the magnetic north pole and the true (geographic) north pole.
