I don't think security has been holding this up. Security is an issue in
OSGrid, only, but there are ways of mitigating it. The major hold up is
that it's not trivial to do the handover of these objects, and no one
with enough technical skills to do it has had enough motivation to do it
in core. I tend do to this kind of stuff (moving things around servers),
but, as you can see below, I don't have any motivation to do it, because
I believe that border crossings SL-style are an inferior solution to the
problem of moving vehicles within large areas. Instead of following that
solution, I invested my time in figuring out how to do co-simulation in
order to avoid borders in the first place.
This is my perspective on the issue. I can't speak for others.

Thank you - the comments are very interesting and while I was aware of
the security concerns, I didn't realise that was a big part of the
hold up. I assumed security issues would be the equivalent of walking
across a border.

I'm sure vehicle border crossings are important for some situations.
For me, they got a lot less important now that OpenSim supports
variable-sized regions. There are also alternatives
(co-simulation) to moving vehicles along very large areas that are
able to avoid crossing borders altogether, therefore avoiding the
"bumps" on borders and the extra load that moving vehicles and
crossing borders entail. These 2 things (varregions and
co-simulation) don't exist in SL, but they're superior in some
respects, because they avoid crossing borders altogether; it's
much smoother, keeps the load down, and avoids running into
security issues.
Here's a video showing a large-scale traffic co-simulation:
https://www.youtube.com/watch?v=291yE_9eefU#t=4m02s
Co-simulation means that one simulator has part of the objects, in
this case the vehicles, and the other simulators have the rest of
the scene objects. The vehicles never cross borders, even though
they move along very large distances (in this case, 3km x 1.5km).
I talked about how to do this at OSCC'13.
This is not to say that I don't support adding proper vehicle
border crossing support to OpenSim, if someone cares to do it. +1!
But I would never trade the borderless way of moving vehicles for
the SL's way of moving vehicles, so vehicle border crossings has
been very low priority for me, personally. One of the perks of
reimplementing the server-side is that we can do things that can't
be done in SL!
