Drivers to Stay on Track and if they dont???

Without entering into the current controversy regarding Lewis Hamilton cutting the chicane. I would like to invite discussion on the pros and cons of the track improvements introduced over recent years and the effect it has had on Formula 1 which have basically led to the issue in the first place.

Kerbs and walls except on street circuits have largely been eliminated in the name of safety plus other measures to reduce car speed have been imposed such as smaller rear wings , narrower and grooved tyres. It could be argued that aerodynamic engineering has largely negated these measures at the expense of mechanical grip and efffective overtaking ability when close to the car in front - but that's another issue

Without claiming to be any kind of expert and only an armchair spectator of many years it is my opinion that the track safety issues have made possible and have led to issues such as Hamiltons chicane jumping issue .  We see cars often drifting away from the "proper ' track line onto nicely prepared "concrete" grass painted green and also to the kerb jumping and straight lining of chicanes.

Correct me if I am wrong but i thought chicanes  and corners were there to slow drivers down?!

Whilst i understand that having drivers dropping out of the race bogged down in gravel because of a simple mistake is not what most fans want to see I think we have gone too far in forgiving drivers for these mistakes. ie drifting off the "track".

The track in my opinion is that black stuff called asphalt and if you cant get around the corner at 150 mph or whatever and stay on the track then the driver must slow down to an appropriate speed to do so. the same applies for straight lining chicanes and jumping corner kerbs.

What I am suggesting is that we need to bring in an "electronic" brick wall or kerb, one that will get the same attention as the physical barrier without the pain or damage! .

This would have the dual effect of slowing cars down which is what i understand the FIA wants to achieve and also would help clarify electronically where the track begins and ends.

Of course its open to suggestions and comments on how best to achieve this however in this day and age of electronics what is wrong with trackside and in car sensors and something  relatively minor such as a 1/2 or 1 second penalty each time a driver crosses the electronic track side line? Due to the 1st lap scramble and melees maybe it could be switched off for the first lap until it gets processional?

This is obviously highly contentious at this time of retro penalties but i believe could be workable as it would be known immediately and as long as the driver took steps to correct his line and speed then he would be unlikely to repeat his error numerous times. Any deduction would be obvious at the end of the race and unlikely to change the end result unless we had a nose to nose finish.

I can hear all the ahh but what if this and what if that? etc  but remember years ago the track was the track and if you were off you were probably seriously injured or certainly out of the race. Drivers did their utmost to stay on the "Black Stuff". Teams would not have to be building cars tough enough to bounce  over kerbs - leave that to the rallying boys.
