That's called in ancient Gteek, who wrote and read that way, "boustrophedon" How the ox plows. Reading from Left to right and then joggin eyes back left to read to the right is stupid for 2 reasons.

First of all, we are RIGHT visual field dominant in 95%. So we should start reading from the R to L as most languages do, including Nihon and Hebrew. Next we should read boustrophedon for even more speed.

Sadly, it's based upon dreadful "that's how we do it" rather than empirical reason.

Same problems with driving. Brits and many in UK & CW drive L side of road. Head on collisions are high speed and we attend to and avoid those best, driving on the Left.

That too is a real problem.

Many of our arbitrary customs are similarly flawed and not in our best interests. no one bothered to think.
