Motor cycle keys also have teeth on either ends.

There are many locks that accept keys with cuts on either side, and some that have keys with no cuts, and instead have dimples on all four sides.
Car keys usually have two sided keys so you can insert them into the lock in the dark and it will work either way.
Low tech keys are limited in the possible number of combinations that they can have. For example a cut may have 8 different depths, and the key might have 8 places for cuts. But you can't have too deep of a cut next to a shallow cut or the key will get stuck in the lock. And you cant have only shallow or deep cuts either, or all of the same cut. These are too easy to pick. So there are not really 8^8 possible combinations. But there are a lot. I even wrote a program one time that would figure all that out! Wow that was a long time ago!

Keys with notches on one side or both determines the amount of combinations available for that lock.
A home lock has only one side notched as it is unlikely you will just walk up to another house and try your key, let alone have it work.
Since there are millions more cars made per year than homes built they need to increase the available combinations for keys.
This reduces the risk of someones key being able to open, start, or something on another persons car.
In my 15 yrs of auto industry I have encountered 2 keys that were for other cars but did open a different car, it can happen even though very rare.
Its like a lottery, the more numbers or notches that are there, the bigger the out come of possible number set ups.

Well, they're not.
But the reason car keys have 'teeth' (or cuts) on both sides is that the person using the key is the mass consumer - and making it universally easy to insert the key into the lock addresses the capabilities of that customer.

They are not. Sometimes you will find locks for padlocks with teeth on both sides. My house key has teeth on both sides. The more I think about it there are lots of keys that have teeth on both side. Sorry.

to maintain morons and drunks from shoving them in the different way up and having to re-key the excellent motor vehicle. A doorknob may be bumped off quite surely with a screwdriver, yet removing a steerage column is purely too much like artwork. Mopar, i.e. Chrysler started that trend BTW. Chevy and Ford used to have one sided keys, long term in the past. distant places automobiles have been constantly 2-sided. yet another occasion of foreigners questioning they are smarter than individuals.
