Hey, I remember seeing this is that Ewan McGregor thing on Discovery. It was called "long way round". Most excellent show!
Yeah, Siberia has bad roads. Not to mention that if you get on the road and are stuck there is no help of many hundreds of miles. not to forget
getting killed by the wildlife as the road travels through the Siberian forest.
Another interesting thing I learnt from the show was that the main road that travels through Siberia from East to West was actually built by thousands
of prisoners from the Siberian gulags. The road was built without any machinery and thousands of there prisoners died making this road.
