I will start by saying I am only a fan and not involved in any way.
But here's the question. I spent yesterday at snetterton on a lovely sunny day for £10. The racing all day was close even the 3hour race changed lead on the last few laps. I was however one of the few spectators there,rom where we were it looked like the more racers than fans.
As this is cheap to watch what is going on.

This.

good racing yes but its not really glamarous and there arent any real "names" racing. If they had some pro drivers racing then this would increase the crowds. Or if top gear entered every race...

I would attend more if it were easier to find out when they are. I probably haven't looked in the right places to find out about it though.

The cost of entry is very high for essentially club racing thus average grids leading to lower spectator appeal.
There are many costs in racing and some racers do not have the funds hence cut down on tyres or use friends to act as mechanics but the entry fees have to be met.
The circuits charge and thus entries go up about 30% on the year in Britcar hence less cars with resultant lower appeal.......... maybe the TG boys would help

This weekend you had Michael Caine, Mike Jordan, Luke Hines plus Sarah and David Moore runing in a support race who are real future stars, to name but a few or do you expect F1 or current touring car drivers, yes it is more grass roots but that what makes it cheaper to go and watch but no less great racing.

TV coverage.

Unfortunately motorsport is a one shot thing, and if a team and driver doesn't make it to F1 then they're an also ran, or even a failure. At least from a UK perspective.

I used to think the same about Champ Cars, then about FIA GT. Great racing, great cars, great spectacle, and yet fewer spectators than a Sunday League game or a minor county cricket match.

There's just not enough space on the major channels for two big motor racing series, and F1 has it all stitched up!

The three rounds of the BTCC we went to last year only offered a pit walk not full access to the pits. Gt is much better.

The circuits see spectators on "non-major events" as a hinderence. You (the viewing public) are not really wanted by them, because they have to provide security, concessions, etc.... just to feed the twenty six of you die-hards that go along an watch club motorsport.

If they changed their marketing ethos to fill the grandstands, put on racing that people wanted to see, then drivers wouldn't (shouldn't) be burdened with the circuit operating costs, but should have a share of the gate for their part in entertaining the paying public.

Only then will the sport command it's place in the media just the same way that a bunch of over paid jessies that kick a ball about once now then do.

Some of Mr Tuckers ideas may often sounds hair brained, but in many cases they are great ideas, just that they come at the wrong time. The V8Utes would be good, and the stock-block powered LMP type cars would also be good - IF they could get people to commit to them. The trouble is - people don't want to commit to it at this time.
He ran "V8 Supercars" - which had the support of the likes of Andy Rouse as an outlet for the stillborn SCV8 cars, among others - though Andy didn't turn up to any race meetings with cars....

I also agree that the Britcar open paddock/pits is very welcome. If you have sponsors, you have to meet your public!!

I'll declare an interest here- James Tucker is my brother-in-law and I raced in the early days of Britcar, but not recently.

Britcar have had combined grids in the past when numbers dropped away according to the prevailing economic circumstances of the times, but there was the problem of the disparity in speeds between the quickest and slowest cars.
Originally all the races were at National B level, but only the Production class is Nat B; Britcar main races and the 24 hour race are now National A. This was a ruling from the MSA and nothing to do with Britcar, but the split will be essential to continue to allow Nat B licence holders to race.

I think your comment about "crackpot ideas" is rather rude. Britcar itself was considered a crackpot idea by many in the motor racing establishment, but it took James to drive the idea of endurance racing forward when nobody else was interested. He was also prepared to put his money where his mouth is and build the whole thing from scratch. He's always looking for ways to expand it and get more people racing. This is why he's always coming up with new ideas, but if people don't step up and support him then nothing happens. You can't blame the chap for trying
