Thoughts

• Everyone has driven different vehicles. Gas gauges vary greatly. My 2000 Jeep Wrangler's gauge quickly goes to half way, but then takes a long time to travel to empty. My 2005 Mazda RX-8 was just the opposite. How about yours?

• Have you ever noticed the green light at the entrance and exit of escalators? Do you know why? For safety.

• Do you know how US Federal roads are numbered? Numbering starts in the Southwest heading Northeast. Odd numbered roads are South/North (vertical) and even numbered roads are West/East (horizontal). Exits count South to North and West to East. They are numbered by the mile. If there is more than one exit in the same mile the number of the exit is appended with a letter (A, B, C, etc.).
