That's nice, but it's easier said than done. Even the most attentive drivers will occasionally drive intuitively. It's human nature.
For example, how many of us would notice new or modified turning restrictions on an intersection we've used for years? I know good, safe and accident free drivers who've made illegal turns on an intersection with a new turning restriction for months without realizing what they've been doing. Likewise, remove a stop sign from a regularly traveled routed, and I bet some drivers would still stop at the intersection. After getting used to having the stop sign there, people will no longer look for the sign and intuitively stop. They aren't bad drivers, it's just human nature.
This is the reason why those eye-catching "NEW" signs often have to be installed where there's new driving restrictions.
