RE: Side Mirrors

These could be eliminated if we had cameras mounted to view both blind spots and monitors to display the views. I would think this will have to be a factory design and install to increase aerodynamic efficiency.

RE: Increasing Tire Pressures

Probably the best thing an individual can do to increase rolling efficiency. Auto manufacturers post a low tire pressure recommendation to achieve the best ride feel. Tire manufacturers post the maximum recommended pressure on the tire sidewalls. Maximum pressure will give the least rolling resistance and best fuel economy but the harshest ride.

For Christmas, I received a tire pressure monitoring system. It uses a tiny battery, pressure sensor, lock, and RF transmitter on each wheel. The Digital monitor is an easy mount on the dash. The readout is in PSI to 1/10 of a pound. At night, it back lights for about a minute, long enough to view the pressure in all four tires. It includes three low pressure warnings alarms. I think the engineering, features, and quality are superb.

Optimism doesn't wait on facts. It deals with prospects. Pessimism is a waste of time.
