Sir
Just be safe and drive within your car limits, with more people in car it becomes more risky for the driver and car to remain stable.
BTW, I witnessed a black 1988 Accord with blue number plate that overtake me when I was @ 180km/hr in a 05 VTI Manual, it had a H22 in it, I just hit the brakes when I judged the car's velocity.
It is useless to speed up with seriously modded cars.
