| Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}/MJ25.6.30 contd. -8- special motor roads, all encourage high speeds. We know of no big car used on the Continent that does not fit ventilated bonnets. Therefore, wal while we are better off for cooling than we have been before, we think we shall still have to equip cars habitually used on the Continent with louvred bonnets. We shall also have to do all we know to cope with the high speeds that can now be attained on some English roads. We are carrying out a further series of tests to see how this can best be accomplished. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
