I will unlock this in few days.
The lock is there to give puzzlers the chance to play and not to stop the 'usual suspects' to score. 
Time for a clue: the name involved is not obscure and connected with several makers in different ways...

Is the name connected to French "sans permis" manufacturers active during the eighties ?

Yes!

Now you are definetly there!
It should takes minutes now.
I need a precise answer: builder and name (or nickname) of this vehicle.

Le Hanneton by Jacques Riboud ?

(I can't see a lock for Djetset and the "minutes" are elapsed so I thought I might have a go at it)

Edit: the puzzle car is featured in an article written by Jacques Riboud himself, titled "Trois roues et une pédale de frein" (three wheels and a brake pedal) which explains the concept behind the vehicle. Maybe this is the nickname you're looking for, as the Hanneton seems to be another vehicle.

Yes.
I did not set a lock because I am trying to change some things at Autopuzzles...for example the hunt for points.
I am the 1st one who was after each and every point and I can't teach no-one about, but still I'd like more ...attention to other players.
If you have a doubt about, why don't you just wrote it that way?
Something like "I know the answer but don't know if I can have a go..."
Probably because if it was not you, there was another one right after you with the answer.
This is exactly the stressful feeling I'd like to avoid in my puzzles.
I know it's technically my fault, but I did not set a lock on purpose.
There were no locks before...they had to be introduced to avoid these situations, but we can apply some judgment ourselves to admit when a point is lost or is going to be lost soon.
I am not saying you did not earned your point (you play like no others and I like your style in getting close to the solution via different angles and a lot of questions) but sometimes we have to let them go...
Anyway point for you and for Djetset: I am sure he would have find it as well

[oko94]

I understand your point of view, but as far as I'm concerned I like things clear and simple : if it's locked, it's locked, otherwise it isn't  (I'm a software engineer, you know).

[Djetset]

Wow!!  Not sure what happened here, but I wrote 'Vitrex' at Nice airport, just before boarding a plane and switched my 'phone off, and now I've just landed in the UK and I'm somewhat surprised to this one solved. especially as my next post was going to be Riboud as he built a handful of velo cars in the 1970s.  Anyway, looks like events have rather overtaken me here 

[Carnut]

At least you did get a point Djetset, although maybe you'd rather not have since it takes you to 399 points; 1 more and you won't be able to compete in some of the Pro puzzles only open to those with fewer than 400 points..!
