Multiplexed at what rate? Faster or slower than human eye

The rate is hard to estimate - maybe 60-200 Hz? You know how - if one
sweeps one's eyes from side to side when looking at a time multiplexed
light source, it looks like a dotted line? Well, on two occasions at
night, I was shifting my eyes when I noticed the taillights on certain
new models of automobiles are time multiplexed. I'm just wondering if
anyone knows anything about them - like what is the advantage over
constant current LEDs? Am I the only person in the world who notices
such trivia? :-)
