It's the opposite with me. I speed more in my Camry than I do in the Cobra, as long as we are talking about regular day to day driving with traffic and not taking advantage of an empty stretch of road.
The Camry is so weak and underpowered that I feel the need to maintain a higher speed so I have momentum on my side in order to stay with traffic and not have people riding my ass or swerving violently around me simply because their car is faster. I can stop quickly if I have to, but getting that speed back takes much longer. I fear having to brake suddenly or reduce my speed drastically due to lacking acceleration to quickly gain back lost speed. I have to plan maneuvers well in advance of other vehicles or I am stuck with the scraps on the floor after everyone else has made their move.
The Cobra is the opposite, I have endless acceleration and feel more confident in my ability to alter my speed on a whim on my own terms, and don't feel like I need a "head start" or feel like I am a bottleneck with my foot to the floor and going nowhere. I can put distance between myself and other traffic with ease and not feel like I'm being rushed. With the ability to quickly come up on traffic in front, there is more discretion on when to floor it and when not to, and even though there is more power, I am more cautious about using it.
Thus, in the Camry I am doing 100 in the left lane and nervously watching my rear view. In the Cobra I'm doing 55-65 in the right lane with the windows down just enjoying the sun and the exhaust notes not really giving a flying f**k about what the rest of traffic is doing.
Used to be an excessive lane changer and ride within inches of bumpers, but after a while you realize it doesn't save any time, makes you look like a dumb ass when you are the the 10th light with the same person next to you (or even behind where you started), and you realize it averages out and you aren't actually getting anywhere faster. It's far more effective just to leave 10 mins early than to leave 10 mins late and try to make up for it.
These days I enjoy 0-45 bursts and a kick in the seat and heel-toe down shifting into a banked off ramp at 55-75 mph more than excessively high speeds.
