Indianapolis to use soft barriers
The energy-absorbing barrier features a welded series of steel tubes connected to the concrete wall by a series of steel splices and the gap between the metal and concrete barriers is filled with polystyrene sheets. The wall was designed to give way enough to save the drivers involved from major G-force injuries and proved to be remarkably successful during this year's Indianapolis 500.
Although the barriers are useful on speedways, there have limited use on F1 tracks as the angles of impact involved are very different.
