about Long Island

Found this on a National Park Service website ... I'm amazed the government permits its staff to be so flip. But, is it true?

Traveling Trivia:

- Travel on Long Island is best measured in time, not miles.
- The average speed for freeways is about 30 miles/hour. Yes, you might go 70 miles/hour for three minutes, then it's 5 miles/hour for the rest of the trip.
- Getting to Long Island involves paying a toll for a bridge or tunnel.
- Leaving Long Island involves paying a toll for a bridge or tunnel.
- Parkways in New York were designed in the 1930's for use by passenger automobiles. Their low overpass clearances are purposely designed to prohibit
use by recreational vehicles, commercial bus and truck traffic. Their on-ramps and off-ramps can be frightfully short.
- Expressways are open for all traffic which includes recreational vehicles, commercial buses and trucks.
- Many traffic ways in the metro-New York area are prime habitat for concrete construction barriers, orange construction cones and barrels.
