Take a look at this cycletrack in Boulder, CO. It includes parking stops along with the usual flexposts, thus providing strong protection against cars.

This particular cycletrack is on Baseline Road, a busy suburban arterial with relatively high-speed car traffic. It’s easy to understand why cyclists would want more protection there than on a slower-speed urban street.

This design is a stark contrast from the more urban cycletrack in downtown Boulder, where a lush (and expensive) landscaped median provides the protection from cars.

Between the two designs, one can see the range of options.
