The area of the freeway on the outside of the solid white line is meant for:

The area of the freeway on the outside of the solid white line is designated for emergency use only. This strip of space is specifically intended to provide a safe area for vehicles that experience unforeseen issues, such as engine failures or flat tires. In these situations, vehicles can pull off the regular lanes of travel, minimizing the risk of collisions with moving traffic.

This is a safety measure, ensuring that any breakdowns or emergencies can be handled without further endangering the driver or other road users. Utilizing this area for non-emergency activities, such as parking or refueling, is not permitted, as it could lead to hazardous situations and impede the movement of traffic. Similarly, it's not intended for bike lanes, as bicycles should be safely integrated into the traffic flow or designated bike paths, not on the freeway.
