In my experience pencil gauges degrade in accuracy over time and have a tendency to get bent, at
least with my abuse.
That said I use the floor pump pressure gauge for my bike with a cheap pencil gauge in my bag for
emergency use.
For my street car I use the pump gauge at the gas station or the gauge on my compressor.
While it is possible to find a wide range gauge that will cover both automobile and high pressure
bicycle tires, rightly or wrongly, I would wonder about the accuracy at the extremes.
For any kind of serious motorsport, If you can afford to race you can afford a decent dial gauge
with a flexible hose and a release button. Not to forget a decent tire pyrometer.
If you want a decent schraeder type pressure gauge for car tires, a racing oriented "speed shop" or
tool suppler will probably have a few to choose from.
