Yes, but give them their own lane. The 70 and up lane. And they need their own roads. Instead of the highway, create a lowway under the highway for the 70 and up. And make all the street signs way bigger. For example, instead of regular stop sign size, make a billboard that say stop. Audio traffic lights that scream goooo! real loud when the light turn green. When it turn yellow a voice come out real loud and say nikka slow down!
