Disc brakes;

To which one could add.

There WAS a time when even windshield wipers were considered rather
'sissy'; and as for heaters in cars in a North American winter, they
were considered unecessary. Remember those bulldozers and snow ploughs
with the driver merely protected by a canvas dodger around his waist?
Heated/air conditioned cabs???? What do you want them for?

It IS also rather amazing that in recent years the usage of certain
terms has been perverted and are now often used negatively.

As was the word 'Communist/Commie' was back in the 50s! (In other
countries (with democratic systems) a few Communists even got elected;
at least one knew who they were and what/who they stood for)?
..
These now negatively charged words now include 'liberal' (small L) the
true meaning of which is broad-minded, willing to consider other
points of view, generous etc.
..
Also the word 'Socialist' which some will argue as espousing the very
Christian values of equal treatment, the support of one's community,
responsibility to it etc.

Strange world. Eh?
