Rolling stops in cars “approximate” full stops closer in the sense that 5–10 miles/hour is closer to 0 than it is to the 30 miles/hour they were traveling before.

By contrast, 5–10 miles/hour on a bike is about equally far from 0 and the 15 miles/hour the bike was traveling before.

The biggest difference though is that getting hit by a car doing a rolling stop will put you in the hospital and possibly kill you.
