All of the above practicalities are nice, but it's the hyper-kinetic nature of the Fiesta ST that really makes it addictive in daily use. It has almost a motorcycle's agility in traffic, and with the COBB Stage 3 boost modifications, it can outpace all but the swiftest stoplight adversaries. The steering happens right now, and there's very little inertia with which to deal. In the elephant procession that is rush-hour suburban-Suburban traffic, the ST darts and dives with sublime grace. Viewed from above, it would look like Usain Bolt running through an endless procession of medically obese Walmart shoppers.
