7. Minimal risk: In a race car using manual transmission, there is a chance of a mis-shift occurring with the ‘H’ pattern. In other words, you miss the intended gear and apply another one. It can happen when you let go of the clutch too soon or get confused with the location of the gears. When this happens, the transmission can get damaged and cause the components to wear quickly. The worst case scenario is the engine could blow up, endangering your life. The consistency of the sequential gearbox does not allow mis-shifting.
8. More space in the cockpit: Race cars are small and compact. A whole gear system will take up a considerable amount of space in the cockpit. Since the sequential manual transmission consists of a pull/push lever, it does not take up much space. You have a paddle-shift system where the gears are activated by hydraulic or pneumatic actuators and paddles are used on either side of the steering to control acceleration.
Though the sequential gearbox gives the driver more freedom when changing gears, it doesn’t qualify as an automatic transmission. At the core, it’s still the subset of a manual transmission. In Europe, many mass-produced vehicles are being fitted with mechanisms similar to the sequential gearbox. You may soon find it even in high-end cars being manufactured today.
There are drivers who still prefer a standard manual transmission in cars for everyday use but the sequential gearbox is a superior choice when it comes to auto racing.
