The Lithiumate Lite has a "Throttle reduce" output. It's an electrically
isolated, electronically controlled, variable resistor. It is normally open;
as the battery starts getting close to empty, the resistance across that
output gradually decreases, down to 0 Ohm when the battery is completely
empty. You connect that output across the throttle pot, to get a more and
more sluggish throttle response, as the battery nears empty, down to no
throttle response when the battery is completely empty.
The Lithiumate Pro has a DCL (Discharge Current Limit) 0 to 5 V analog
output that can be used in a similar way to reduce the throttle range.
The MiniBMS has a buzzer that sounds when the battery is empty, as does the
Manzanita Micro BMS.
So, yes, the EV enthusiast does have access to BMSs that provide a warning
to the driver.
