Race app takes the vehicule that passes the line on last lap

When racing, the app will take the vehicule that passed the line on the last lap, and not the actual vehicule that did the lap. For exemple, I did a 5:52 in my Jester RR on lap 3/6, she blew up on last lap so I stole a bike to finish the race so my time is saved, but when I finished the race, it's now saying "Double T" for my 5:52. This means that some guys can take a super, do 5 lap of the best times, swap car on the last lap and claim they achieved in that car.

Step :
Start a multiple lap race
Get a personnal best time with vehicule 1

Take vehicule 2 on last lap

Your best time is now registered with that car

Expect behaviour :
The app should register the vehicule passing the finishing line per lap and not just the vehicule that passes the last lap finishing line.

Actual behaviour :

Registers the vehicule for the best lap with the one that passes the last finishing line

PS : Possibility to change the vehicule in that lap record back to my Jester RR?
