They could easily make a rubber insert that could be squeezed into the gap, it wouldn't have a chance of coming out. ?

A gap like that has to be more violently jarring than a kerb with a radius on it, particularly if they hit it square on.

I always thought that this idea of building a F1 bridge was a gimmick. Something new for Bernie his marketing people to get excited about. Exactly what has Valencia paid for in buying their F1 franchise? This attitude is typical of arrogant franchisers who believe that their product is so perfect that all they have to do is allow a franchisee to use their product and all will be well. What about providing some product support?

Valencia have paid their money and some more in getting the circuit ready, but they have been let down badly. As soon as the bridge was commissioned, an inspector from the franchiser should have been there to either give it a red or green light. To wait until this time is just ripping people off.

I also wonder what kind of safety concerns will be raised when we get to our floodlight match.

Has anyone got any quotes from Bridgestone after FP1 & FP2?

Hirohide Hamashima - Director of Bridgestone Motorsport Tyre Development: "This is a very nice street course which is, in many ways, similar to a permanent facility. There are long straights, meaning a good high speed battle with speeds over 300kph, and slower corners, meaning good braking technique is required. It is a very technical circuit, for example there is an adverse camber section before the bridge which makes matters very interesting for the drivers.

Both compounds performed well on this first day and the track grip levels improved dramatically during both sessions. At this stage it is very difficult to say which will be the preferred tyre for qualifying or the race as we have a lot of data to digest and drivers and teams are still learning how best to tackle this exciting new venue."

No problem at all

Bridgestone: No problems with tyres

I imagine the downforce would suck such a solution out straight away. If drain covers can be sucked up without being welded down, I don't think a rubber stopper has much hope ;)
