Missed opportunity

To me, using 2G for newly minted eCall box (to be rolled out in 2015) strikes as a huge missed opportunity. 

By investing in LTE, for example, like what GM is planning to do, there seems to be a variety of business opportunities for carmakers to mine. Am I wrong about that?

An educational video:

3G isn't totally secure but 2G allows the base station to tell the phone to turn off the security mechanisms and 2G devices by default trust *any* base station.

EU's eCall does not mandate which cellular connection the eCall box needs to use. 

So, it is a choice left to automakers.

Why is 2G less secure than 3G in eCall implementation? Could you please educate me on that? Thanks!

Not only is E-Call a massive waste of money, but if it is going to have 2G technology it won't be secure! It is now trivial to mess with 2G so I worry about the consequences.
