Yes, sometimes you need to stop the car, because changing the tires
while driving is impossible.
Have you considered using a ClassBox, available from SqueakSource.
Let's change one of the tires while on at full speed: create a new
ClassBox which includes all of your car. In that isolated box change the
tire. If this works out fine, release the changes to the running car's
ClassBox. A more practical Smalltalk example is to change the compiler in
the running system, this needs the compiler.
