Why yes, yes we CAN drive. We can drive just like hearing people do on the roads and highways. We have drivers' licenses and everything. :-)
Did you know that we're even considered safer drivers and sometimes get lower insurance rates?
I hear you now (get it?), "but what about ambulances and sirens?". We SEE the flashing lights. Most of the time we see the flashing siren lights blocks away before you even hear it!
So there's the answer to your burning question. :-)
