Botts dots

And it recently installed small ceramic bumps, called Botts’ dots, at four intersections to deter takeovers.

Compton, near Willowbrook, spent $4,000 to install pavement markers called Botts Dots at popular intersections for street takeovers in hopes it would discourage the practice by making the road bumpy.

Botts Dots helped curb street racing in Lynwood and Paramount.

In fact, it was at times more comfortable than on a conventional motorcycle, because the space between the two front wheels allowed me to straddle the center line and the Botts Dots that sometimes make lane splitting bumpy.

These days, the most challenging driving environments require self-driving cars to make guidance decisions without white lines, Botts Dots, or clear demarcations at the edge of the road.
