Is computer alignment not always 100% reliable?

[lonhong]

Hi guys,
     I went for computer alignment yesterday as my car kept drifting left. After the computer alignment, which i witnessed the mechanic really did his job adjusting the toe, i went test drive. Still it drifted. Then he manually tuned for me again. Now I find it ok but have gone onto the expressway. Is this normal? I never seen computer alignment readings to be off before...

Could it be due to your tyres which are unevenly worn?

Roads are also built to slant to one side to drain away rain water, so you may expereince your car slanting to one side at times through no fault due to your alignment.

Computer wheel alignment are usually highly accurate.

it's could be due to the rim not smooth (just like my previous exp, the rim not in proper shape after hit on big holes on
malaysia road). Sent for "rework" the rim but not able to get the alignment 100% gd again after computer alignment (it still ok afor awhile after alignment, but not for long). By the way, the tyre balancing also faced some issues due to this rim too.

mine i think its not due to rim problem as balancing seems alright...
anyway now i think its better... just dun go back to the same alignment shop lor...

Roads are actually built to slant at a small angle, this is in order for rain waters to be drained down the drainage...it is normal for a car to drift left...

also i heard that it is also for safety reason like if halfway on expressway the driver lost conscious or watever the car will drift itself to the road shoulder instead of the right most lane...
