Increased cost
ConclusionConclusion In the case of active suspension
system, as in any other innovations of automotive technology, today's innovation is tomorrow's standard feature. Inspite of its high initial cost, let us expect to see them in the Indian roads soon. The trickle-down effect will take some time, but it'll happen and when such a time comes we can expect much lesser accidents, less fatalities and more comfort in driving the roads.
