Low ratio steering boxes

Please explain further, how can it be all 3 of these?
Steering is scary
drives very straight
hard to keep in the lanes?
When I turn the steering wheel it seems like I have to turn it quite a bit before anything happens but when it does it seems to be pretty quick. There seems to be a delay in the steering response in other words. The car will go straight for long stretches if I take my hands off of the steering wheel but when driving any sort of semi curving lanes it seems to take a lot of wheel turning to get it to steer and stay smooth. It just seems like it takes a lot of wheel movement to get it to go in the direction I want and to keep it steady in that direction.
