Do you ever use standby on your transponder?

I have had landing aircraft report a near miss when I left my
transponder on accidentally..
At my little Class D airport our rule is standby to warm it up - it does
take a few minutes (at least mine does) - and on upon takeoff.

I make no attempt to turn it off or go to standby while taxiing or
anything else. I've never been asked to go to standby or otherwise
questioned.

This has been discussed before but I'd suggest the everyone can do this
without causing a problem for anyone.

Mine is on standby during taxiing and when I'm flying below Amsterdam
TMA1.
The moment I line up I switch it to Alt.

You should.

From the AIM:

4-1-19. Transponder Operation
a. General
3. Civil and military transponders should be adjusted to the "on" or
normal operating position as late as practicable prior to takeoff and
to "off" or "standby" as soon as practicable after completing landing
roll, unless the change to "standby" has been accomplished previously
at the request of ATC.

Yes, when flying in formation with others and I'm not lead. Lead
squawks, the others use standby.

Not a terrible idea. If the tower doesn't like it they can say so.

Personally, I turn it on at engine runup -- never on the runway. If I
forgot to turn it on, I don't think reaching over and switching it
would be a distraction. But then, I fly enough that I don't have to
look or even think about the transponder switch.

Some transponders have a 'ground' mode. The Garmin G-1000 turns its
transponder on and off automatically.

The Garmin transponders automatically turn on and off (my GTX33 does)
based I suppose on noticing that the encoded altitude has jumped since
it was turned on.

The the SL70 (formerly Apollo) transponder also has an engage mode if
an attached device (like your GPS) says it is now moving at a certain
threshold speed.

I was taught to use standby when on the ground and it says to do so
right in the manual.
