The Challenges You're Facing Right Now?

Hi, I have been following your progress for the past few years. So today you have made changes on like the lane detection. You said that like previously you were doing instant semantic segmentation now you guys are built transform models for like building the lanes. What are some other common challenges which you guys are facing right now, like which you are solving in future as a curious engineer? And the second question is really curious about the data engine like you guys have like told a case like by the card is stopped. So how are you finding cases which is very much similar to that from the data which you have so little bit more on the data engine would be great. Okay. Thanks so much
