Its not ?autofs? specifically (which is a simple thing) but udev talking to
udisks, allowing your login session to use udisks to mount the volumes if
allowed by PolicyKit, speaking through dbus.

Yeah.

How do I get the ask-first behavior?
How do I tell what makes Lifestudio special?
When I plug in an SD card through a USB adapter,
something asks what I want to do and lists options.

In case it helps:

Could you provide more context information? 
Appliance setup, Dekstop setup, server setup?
There exist a lot scenarios where something 
happen automagically?

As I said earlier, this behavior isn't autofs.  Don't blame autofs.
autofs is a nice tool.  autofs is easy to understand, enable and
disable. 

To disable the auto-mounting of USB disks via udisks, you'd need to
set up a custom udev rule.  Of course, it's hard to know which
existing udev rule is catching your disk, as you said, behavior is
different with an SD card than with a USB disk.

For CentOS6, the udev configuration for udisks is:
/lib/udev/rules.d/80-udisks.rules

... while in CentOS7, the udisks2 udev config is:
/usr/lib/udev/rules.d/80-udisks2.rules

You'd put the custom rule in /etc/udev/rules.d/.

These rules depend on the device name, vendor and model ID, drivers
used, etc.  You'd have to write a custom udev rule either for that
particular device, or something more generic for that class of
device.

You might want to consider just disabling udisks{,2} entirely, if you
don't use the features.
