For thought experiment, assume a five-mile stretch of road with 60mph limit, and "time of travel" ticket kicking in at 65mph. It takes 5 minutes to drive legally, and if you take less than 4:37 then you get the ticket. Assume you drive at 60mph and then you suddenly have to "speed up" to 80mph to avoid a situation. How long can you drive at 80mph before you're ticketed? 69 seconds. If you're driving for 69 seconds at 20mph above limit then you're not "avoiding a situation". You are speeding.
