I use sport mode fairly often on my '18 2.0 EX-L when I want to drive fast. Before kids, I had a GTI, RSX Type-S, 200sx SE-R, and Sunfire GT (in reverse chronological order). The 2.0 Accord is the fastest car I've had, yet has enough room for my family of four. With sport mode, I value the superior throttle response and engine braking. I love being able to lift off the throttle to stop accelerating or slow down and then get back on the throttle without having to wait for the transmission to get back into the right gear. With the tires on the EX-L, however, I've found that I spin the tires too much when accelerating onto the highway from a stop, so I have to leave it in normal. Apparently traction control is less aggressive in sport mode.
