its less about speed(k ehni hove ya oni hove minimum), look average hundi ik constant value.. so its about oh speed jedi tusi jyda ton jyda distance layi continue rakh sako...hun oh 60,70,80,90,100,.. (agge rab rakha) koi v ho sakdi
bas appe aajao average.. kise particular number te depend nae kerdi average.. IMO but eda matlab eh v ni k 40 te chalan lagjao.. 60 ku ban e jandi 5 gear tak :P
braking te v depend kerdi.. instead of breaking use de acceleration, ya inj kehlao avoid frequent gear shifting(highway te possible aa) hawa check kerva k jao highways te.. hawa ghat hove tan de-acceleration ch distance cover ghat hunda sheti slow hojandi gaddi race shadde te... te avg te negative impact penda..
