Good observation. I will check the events where this occurs and reposition the start further back so that there is enough speed when starting the lap.I found another issue. I'm doing Seasonal #4 in the Coffee break now. Ordinarily you can do lap after lap until you sort of master the car and track. But something has changed and now you only get a single lap, when you complete it, you have to restart.
This will be a bit of a problem because superlap events often have you starting with the AI beginning the lap at a low speed. I think some seasonals might be impossible to gold if you can't continue lapping until you get the entry to start line perfect.
