Using highways as secondary airstrips is not that unusual or new since every air force is aware that their airbases will be the first targets in any conflict. Countries that are known to use (or at least practice using) highways as airstrips include
- Sweden
- Taiwan
- Singapore
- Pakistan
- Egypt
- Poland
- (ex-) West Germany
- South Korea
Looking at this list of countries, you'll notice that all of them have one feature in common - their strategic depth is limited. In other words, no matter where their airbases are located, they are still within reach of their potential rivals in any conflict.
India didn't have this problem until very recently as many of our airbases are located well behind the front-lines of any conflict. However, now that our rivals now have the tools to reach well behind the front-lines using air-air refueling, cruise missiles and ballistic missiles, it is worth the air forces time, effort and budget to practice such emergency measures.

Even with the nose drooping down, the visibility from the the Concorde's cockpit is much poorer compared to other aircraft of a similar capacity. However in the incident which caused the crash, even stellar visibility wouldn't have helped matters.
Concorde had the highest take-off speed of all airliners and by the time the aircraft reached the point where the debris had fallen (from the jet that took off before it) it would be going too fast to do any avoidance maneuvers (most airliners disable the nose-wheel steering once the speed exceeds 30-40 knots). The aircraft had also exceeded the V1 speed (the speed at which no amount of braking and reverse thrust will stop the aircraft before the end of the runway), so even though the pilots knew there was a problem, their only alternative was to continue the take-off, declare an emergency, dump fuel (the flight was on a trans-Atlantic route and was too heavy to land with a full fuel load) and come back to land.
Unfortunately, the debris caused the tyres to burst and the high-velocity tyre debris hit the fuel tank located above the main (rear) landing gear. While the tank didn't rupture at the point of impact, the force of the impact caused a pressure wave in the fuel that ruptured another part of the tank that was comparatively weaker. The leaking fuel soon caught fire which led to the total loss of power on one engine and the loss of the other engine on the same side soon followed. Without enough thrust to climb to a safe altitude or accelerate, the aircraft eventually stalled and crashed.

I don't remember the source since I was on mobile, but one of the news articles said that these were touch and go landings only. Before this (the article didn't specify when), the Mirages practiced approaches to the highway (flying the landing up to the last minute before they cancelled it just before touchdown) before they attempted landings.
