That is a risk, oddly similar to the consequential risk of firing PGM's at a sovereign nation, murdering unarmed civilians, using CBU's, indiscriminate area attacks of non military targets, generally doing the mayhem and destruction that passes within Russia as "help".
Here's the thing though, a cynic would not put it past the GRU, or FSB to have done this, in order to give a justification for Putin to start getting some Moscuvies and St Pete's finest youngsters to join the gang that couldn't shoot straight. I would rate that at the highest level of probability, somewhere lower would be a vehicle defect, and well below that any action by SBU.
Ask the question, "cui bono?"
Ukraine to date has acted with restraint and care, this has all the hallmarks of the gang that couldn't shoot straight, the guys who in 1999 probably bombed 2 of their own apartment blocks to give a justification to give power to.... Putin!

The facts of the matter remain that she is no more, Russia remains an invading country, and the #200's and #300's continue to add up back home in the predominately poor and eurasian ethnic areas of the Federation. How long until the usury by Moscow and St Petes becomes intolerable to the ethnic groups that have been the recipient of the care that Putin has brought about? The last time imperialism was this confronting in Russia it ended with a bit of a tiff, from 1917 onwards to 1924, and then on and off through to 1991.
My money is on this being an inside job, and making a point to Putin or from Putin, using the FSB/GRU. It is in keeping with a country that loves Novachok, Polonium, shooting native reporters etc.
Nutloose comments that the
traffic was stopped they sw[a]pped cars before the blast.... that pretty much points to the FSB/GRU more than any spec ops from the SW. A message from Putin or to Putin, time will tell.
