Consertina on Daytona (iRacing NASCAR)

Tried some Daytona in iRacing NASCAR Class C Maconi Series - Fixed to air out my latest livery, Tookie world order!
But it didnt start that well, bit slow quali and started a few rows back.
But on lap 1 for some reason P3 the Nr5 Car decided to lift and demonstrated beautifully the consertina effect and car behind me didnt observe the science lesson and ejected me to the infield so i went from leadpack to last on Lap 1 and without a tow
