deep thoughts

Questions I ponder on my way to work:
1. Why do motorcycles qualify for the HOV lane?
2. If 610 is a loop, why is it still an interstate? Doesn't being a loop kind of make you entirely intrastate?
3. Why does Houston like to merge two freeways of 2 lanes each into one freeway of 3 lanes without any warning to the people in the two innermost lanes? It's almost--though not quite--scarier than the infamous I-35 onramps.
4. Why do people suck so much?
