The law that had just been introduced in Sweden making bicycle helmets compulsory for children up to the age of 15 had triggered a heated debate on whether it should be extended to include adult cyclists too. To people like us, who wouldn't be seen dead in a polystyrene helmet, the thought that we might be forced to wear one by law was cause for concern.

DU: You can really tell the engineers who've been coddled by cheap access to trillion-dollar infrastructure in this thread.
Why not use machines to make demining faster and safer?
Steel wheels capable of absorbing the effects of anti-tank mines enable this machine to cut vegetation safely.
Numerous mechanical systems, ranging from flail systems to soil grinders, are operational worldwide. However, no mechanical system has reached 100-percent clearance reliability due to the complex nature of the mine/UXO (unexploded ordinance) threat and variable terrain conditions. The term "mechanical assistance" explains that these systems, while complementary to manual deminers and mine detection dog teams (MDDTs), cannot yet replace them in their hazardous tasks. By using mechanical means to clear vegetation and process the ground, the perimeter of the mined area can be ascertained quickly, thereby making it possible for the MDDTs and manual deminers to focus on locating and destroying individual mines and UXO in a safer, quicker and more economical manner.
