The third or fourth corner out of Julian is where it really hit home, on a decreasing-radius dirty left-hander, white-knuckling it with a bunch of other dunderheaded journos. No shoulder, the turn closing fast, leaned way over, too much throttle—all that was left to do was mash as much brake as I could muster. The RDRS adjusted, balanced, reapplied, and bailed me out, big time. Sandy spots with uneven surfaces tested the system again and again, but even if I was standing the big luxo-tourer up with all four fingers on the lever, the brakes—and the traction control too, frankly—never failed to give me a solid contact patch in those tight dirty esses (even if lever effort is a bit on the high side). Credit the incredibly clever Bosch six-axis IMU (inertial measurement unit) for sending all the right pitch, roll, and acceleration signals to the Limited’s ECU and keeping my keister out of the bushes.
