Likewise, anyone else with a reasonable CFD facility could design a lot of the car this way, and outsource the chassis fabrication/wind tunnel operation (budget permitting!). Okay it may not set the world alight initially, but then the team would learn and be able to advance this way, like Minardi/Toro Rosso have done. Toyota's problem is they just don't have the right people or structure within the team. In that case, you can throw whatever money you like at a project, but you're just throwing it away...
Also, the fact that engine regs are frozen, gearboxes must last 4 consecutive races and we have a common ECU, with possible standard wings and suspension arms on the horizon, it all makes it much easier for a new team, as there is less and less for them to do in terms of unique (and expensive!) development.
