By all rights, I should be uncomfortable. Too hot, struggling to keep up with the base-spec Hyundai Elantra in the lane alongside me, and experiencing that very specific sensation of your skeleton trying to vibrate itself apart that comes with driving a classic Land Rover Defender. Imagine my surprise, then — not to mention that of the Elantra owner — when I bury my right foot and, with a snort and rumble, the big SUV launches itself forward like a runaway steam engine with ventilated seats.
