Asphalt Versus Concrete


Maybe you've noticed it too. It seems that tight money in highway budgets across the country and here in Pennsylvania means more worn out concrete highways are being repaired by paving them with asphalt. It's a lot cheaper and faster to pave with asphalt instead of breaking up the old concrete and then rebuilding the roadway with concrete.

I've always wondered in years past why Pennsylvania spent so much money on rebuilding concrete interstates, rather than paving them with asphalt. A good example is Interstate 83 south of York where it meets the Maryland state line. The concrete sections of I-83 in York County were uneven, cracked and created lots of tire noise. Then you'd drive over the Maryland state line and suddenly I-83 was smooth and quiet when the surface changed to asphalt.

The black color of an asphalt highway also means any ice build-up in winter melts more quickly than on concrete because the dark color absorbs heat from sunlight. The worst icing situations I have ever seen were on concrete highways.

GM Bankruptcy Needed


Did you hear the automaker that offers more hybrid models than any company filed for bankruptcy protection the other day? Yes. It’s General Motors. You’d never learn that hybrid fact from the mainstream media about GM. In recent years you didn’t hear much about GM’s hybrids because many reporters were too busy insisting that GM just makes gas-guzzling SUV’s and trucks.

The fact is GM was ready with products that were beginning to take hold in the world marketplace when credit for new car loans simply dried up last year. You can thank all those lenders who decided everyone with a pulse should get a home mortgage for the credit crunch that ultimately forced GM into bankruptcy.

As recently as the late 90’s, GM was still making record profits. But the company also did not put as much of that cash into research and development as some of the import companies and that too ultimately hurt GM. One big reason GM did not that pump enough into R and D are excessive union labor contracts that required the company to spend more on health care for retirees than it did on steel to build vehicles. The bankruptcy will break those agreements. Of course GM originally agreed to those contracts years ago and that was the fault of the automaker’s leadership, or lack thereof.

Headlights Are For Being Seen Too


All the rain we've had this spring has really helped me notice how many drivers do not turn on their car's headlights in bad weather. During some of the heavy rain and spray kicked up by tractor trailer rigs, it's almost impossible to see vehicles if their headlights are off. It just shows how absent minded many drivers are. They think headlights are only for seeing but they are also for being seen. And before you say, "well you saw the cars didn't you?" Yeah. I saw them but it was tough. During an emergency maneuver, other car and truck drivers may not see them.

I always turn on my car's headlights in all weather because several respected studies have shown that accidents are reduced if headlights are used all the time. It's a good habit I carried over from my motorcycle riding days.

Volvo has the right idea in having its car's headlights and taillights turn on automatically when the car is started. I realize that most new cars have daytime "running lights" that come on automatically, but the taillights do not turn on. You need those taillights too.
