Frictions

The "stickiness" involved in making transactions; the total process including time, effort, money, and tax effects of gathering information and making a transaction such as buying a stock or borrowing money.

Frictions

The processes involved in making a transaction. For example, if one wishes to buy a stock, one must first determine the price, conduct research, comply with regulations, and spend time doing each of those things. Frictions include both monetary and non-monetary costs. They are associated with the relative difficulty of conducting a transaction. See also: Friction costs, Frictional unemployment.

I can't see an alternative to friction for (extreme) emergency braking, so perhaps this will open the door for a radical rethink of automotive friction braking technology with the design objective to provide the capacity for only one extreme duty emergency braking intervention.
