* Geographic location: Rural areas will likely have a higher percentage of driving students than densely populated urban areas with good public transportation.
* State laws: Driving ages vary by state, impacting the number of students eligible to drive.
* Socioeconomic factors: Students from wealthier families may have greater access to cars.
* School policies: Some schools might have limited parking availability.
While you can find statistics on driving rates among teenagers in general, it's very difficult to find precise, nationally representative data solely on high school students driving *to school*. Any number you find would be an estimate and highly dependent on the specific study's methodology and the population sampled.
