Another good feature of Motorways is that no cross roads, no signals and fenced all along the side for no intrusion from other hazards like animals and human as well.
======================================
I'm reposting some comments, hope no body will mind.
1st, I met a german couple back in 1998 who travelled through motorway and thier judgement was something new to me. According to them M2 was much better then Autobahn, the reason!!? Well, no traffic congestion, more sun, less curves, less hilly, more visibilty and alot of other praises like beautiful scenery which I suspect German will do compete.
2nd, from http://jackchang.net/vivjack/chapter5.html
This is not just one, check out some american correspondant's diaries 'n visit during afghan war, BBC's... World's Best Train Journeys, based on Baluchistan railway lines and scenes.
This one goes like this....
=================================
We didn't really know what to expect but our first impression of Pakistan was that it was ... well ... nicer than India. The people were very friendly and helpful and it didn't seem quite so dirty. Best of all, there wasn't cow shit all over the place (Muslims eat beef so that solved the problem quite nicely). It was very hot and the air very polluted in Lahore, the first city we arrived in. So we got a bus to Rawalpindi (twin city to Islamabad) the next day.
Next nice surprise: It's a REAL bus!!! Not a cargo truck with walls, windows, roof, and seats bolted to the chassis (like they have in India and Nepal). It was a Mercedes and had air-conditioning that worked!
Then, even more amazingly, we got onto a six-lane motorway (that's 'freeway' for N. Americans) that had a posted speed limit of 140 kph. The ride was unbelievably smooth after all the shakes, rattles 'n rolls we'd become used to. And there were real rest areas with convenience stores, CLEAN restrooms, and mosques. But this was all too good to be true.

Hope this repost won't claim flames!
