The jerky motion in the Civic Coupe occurs when you accelerate hard, let in the clutch, change gears and again when you let out the clutch. Its mostly the enagagement of the clutch and the 'thump' that accompanies the drivetrain engagement when you resume accelerating. I don't recall this on the Civic Si I drove some time ago. If you didn't compare this to other cars, you might think it was normal, and in fact, it's not that difficult to live with if you try hard to shift smoothly. But it's still there, and I call them as I see them. I haven't tried other base Civic Coupes, and I haven't asked my colleagues if they experienced it. Frankly, I don't like to be influenced by what other writers think - it leads to a herd mentality.
Regarding traction and stability control, I indicated that they weren't really necessary because the car only has 140 horsepower, so there's not a lot of torque steer, and as a front-wheel drive car, it understeers gently when cornering limits are reached and is easy to control. With 60% of the car's weight over the front wheels, plus a good set of tires, traction control isn't really necessary if you use your right foot judiciously. Stability control is best on torquey, rear-drive cars that tend to 'spin out' easily on slippery roads. For example, I would highly recommend stability control on a car like a V8 Mustang (too bad they only offer traction control). In terms of passive safety equipment, I recommend side airbags and curtain airbags wherever they're available because there's very little protection from the side if you're T-boned, and statistics indicate that side airbags make a big difference in injury reduction. I'd also highly recommend ABS for extra steering control under panic braking, and a very good set of tires, winter tires where it snows (in Vancouver you can get away with all-seasons).
Thanks for keeping me on my toes.
