OFFICAL R.A.C. CAR TRIALS.
Why Not Increase the Average Speed?
Is it possible to effect an im- provement in the method of run- oing the Royal Automobile Club trial? asks Capt. E. de Norman. ville in the Polly Chronicle. And if it is possible, is not the presont time peculiarly suitable for effect- ing that improvement ?
Before wo go any further Ist me make it quite clear that I am not criticising the R. A C. methods of running their official trials. From fairly
I intimate knowledge should say that few official testa of any character equal the absolute impartiality or the com pleto integrity of the R.A.C. trials.
If a word, they have made a worldwide reputation which is wholly above reproach or sugges- tion of improvement.
It is from an entirely different | (angle,that I suggest an improve. Įmont-an augle due to circum- stances over which the R.A.C. has no cantral. But for all that, i the improvement is none the less desirable.

That Legal Average.
Have you noticed how all these RA.C, tests are run at an average. speed of just under 20 c1.p.h.- generally about 19.6 mph.?
Of course, it is our grand- motherly legislation which is at fault. Though every motorist in the kingdom exceeds the 20 m.p.h. mark every time he goes out-in- cluding the higher police officials, magistrates, and other law lumi- caries-that is still our legal maximum speed. Isn't it delight. fully Gilbertiah?
But because of the top-lazy-to- alter-it inanity, the R.A.C. feels that it should not return the speed of an official test above the 20 m.p.b. mark.
And the feeling reflects every credit on the club. The strict adherence to that principle has undoubtedly been wise in the past.
