They would have had Donington and Crystal Palace.
... which were the shape of the future. More artificial road courses were the way forward, but where they'd have put them is another matter. At least three projects failed during the 30s and several others never even got past first base.

The BARC knew Brooklands was out of date and had evolved the low cost "Campbell" and "Mountain" circuits at Brooklands.
The Mountain Circuit had been all but abandoned by 1939 and unless the BARC gave up 10-lap handicaps Campbell circuit racing was going nowhere fast. By mid-39 Brooklands was being beaten hands down by Crystal Palace, which was attracting larger and larger crowds to better racing.

Racing in Britain was moving towards road circuits as is shown by the Donington GPs, the opening of the Palace track and races on the IoM and Jersey.
The RAC had no intention of going back to the Isle of Man - they'd lost too much money there - and I doubt races on Jersey would have happened if not for the war.

Had finance been available and a way around the noise issue found, then it is feasible that the BARC might have built a road course at Brooklands.
The noise issue would have been the big problem. The residents of St George's Hill would not have been amused ...

It might even have been possible to successfully lobby Parliament to lift the ban on closing roads for racing.
No chance. They would have argued that the legislation was already in place in Northern Ireland, so why introduce it elsewhere? But after the 1936 TT both Ards and Bangor were closed: only Ballyclare was used in 1937 and even that was abandoned in 1938 due to road improvements. AFAIK they didn't even apply for a date in 1939.

Had the E-Type ERA been successful when the GP formula moved to 1500cc in 1940 then the case for all these would have become stronger. As I write this I can see the pig carrying out its pre-flight checks.
Can we please nail this one? There would
not have been a wholesale change to the GP Formula in 1940, although it's my belief that there were moves to run voiturette racing on a more formal basis. The CSI specifically ruled in October 1938 that the 3.0/4.5 Formula would remain valid until December 31st 1940 and I further believe that it could (and probably would) have been extended by at least a year, more probably two.
