Are vehicles designed to pull to the right?
Cars designed for driving on the right side of the road are manufactured to pull slightly to the right. This is to prevent the car from drifting into oncoming traffic if the driver falls asleep at the wheel. ... If your car is pulling significantly, it's a good idea to get it checked.
Note the word slightly.

Why does my car pull to the right on the highway?
The most commonly culprit is your vehicle's wheel alignment. When your vehicle is properly aligned, it is at optimal performance. Poorly maintained roads and hitting the curb can throw your vehicle's alignment off. This can cause your vehicle to pull to one side, and can also cause uneven wear on your tires.

Why does car drift to the right?
One of the most common reasons your car will pull to one side is because the wheel alignment is off. When your wheel and axles aren't lined correctly you'll notice your steering wheel – and the whole front of the car – pull to the left or right. ... However, a more serious symptom of misaligned wheels is uneven tread wear.

Why do cars always veer to the right when you let go of the steering wheel, rather than straight forward?

They only veer to the right on vehicles made to be driven on the right side of the road. Cars built to drive on the left side veer to the left. Of course the above is only true if the wheel alignment and power steering balance is set correctly. The reason is the caster of the wheel alignment steers the vehicle down hill and the camber of the road to allow water to run off the road provides the downhill. Ie you drive on the right the low side is the right edge of the road so car heads right.
Because of some responses I have had I am going to clarify this a little more.
Car built for LH side of the road may have a little more front wheel camber set on the drivers side to lessen the effect of steering downhill this is why correct wheel alignment is necessary. Cars for the RH side of the road will also have the drivers side camber set more positive than the passengers side. The specification will most likely state a desired camber for example passengers as +0.25 deg +/- 0.25deg giving a possible setting of 0deg to 0.5deg while the drivers side will be something like 0.5deg +/-0.25deg making the camber 0.25 more positive than the passenger side.
Because a manual steering has more positive feel and responds to the wheels better and is heavier there will be no compensation in the steering for road camber and there cant be anyway. Powersteering on the other hand often has a bias in the valve, not much but can often be around 0.25NM. This is to overcome complaints by owners that the steering feels heavier to turn to the drivers side than the passengers side due to the road camber. This will make no difference to the vehicle wanting to turn downhill but makes it easier and less noticeable to the driver to hold a straight line.
If you import a vehicle from a country that drives on the other side of the road it would be pertinent to check the wheel alignment to favour your country if there is a difference. A steering gear if power assistance may need a retrimmed valve or if you convert the vehicle to have the steering wheel the other side you would purchase a gear for the opposite hand in any case. This might not apply for electric assist.
Yeah some people don't know about it, I worked in a dealer for 6 years, we received extensive training on all questions customer could have on new vehicles, so I made sure to state that "unless is way off"
