You did not state what kind of car your driving. I've got a 99 Accord EX
4cyl /manual (150 hp). I live in Colorado. On Interstate 70, the main
east/west interstate through Colorado. I've had no problems keeping up
with cars traveling 70-80 MPH through mountain passes. The highest pass is
the Eisenhower Tunnel at a little over 11,000 feet above sea level. I
routinely drive at over 9000 feet above sea level with no problems. I used
live in California and I drove a 87 CRX 4cyl/manual I've been up Sepulveda,
Cajon pass, Palomar Mountain, Montezuma grade, Big Bear, Lake Tahoe... and I
never had any sort of problems keeping up with traffic. So I don't think
you'll have any problems with Sepulveda pass...no matter what your driving,
although I don't know how the Honda Insight would do but the are automatics
right?

Cheers,

Rick
