[Shotimes] Pontiac unveils SHO successor?

I can think of a few convertibles from the early 80's.  :-)

Easier to push than pull ???  I want to see you Push a log chain, any
questions ??

Try a toy car. No easier to push or pull it.

Better yet, try this. Let's say you are driving with someone, and your car
dies in the middle lane. Do you push it off the road, or do you pull it off
the road?

These examples are as irrelevant as a pencil or rope example. I have had
steep driveways on a few houses, and the only way to get up them in snow
with the SHO way to drive up backwards.

It's an engineering principle called "stability". The tires/engine/etc.
don't know if they are pushing or pulling and they don't care. It is up to
the rest of the mass of the car as to how it wants to move when the tires
try to move. When it involves force, resistance and movement, a "pull" type
system is more stable than a "push" type system.

It's pretty easy to see this for yourself if you lay a long pencil on a
table then try to use one finger pushing on the eraser to try to push it
straight across the table. It may go straight or it may decide to go
sideways. OTOH if you use your thumb and first finger to pinch the pointed
end of the pencil and pull it across the table, it is easy to make it go
straight.

The old joke is that for successful engineering you don't pull water and you
don't push rope.
