sorry i am away cause i still have flu,, dont want to it pass on to anyone.
if driver is right handed. driving a lhd car is more relaxing than rhd,, from the driver's point this is my personal observation not in any relation to traffic.
this set up leaves drivers right hand to work in the centre of car,, eg:. changing gears, smoking, using astray,,(using ph is not good idea while driving but if used with right hand is much easier.
hope you agree with me..
