"It's a big hammer to crack a nut．"This is how one angry parent described the recent crackdown（强制措施）by London police on parents who drop their kids off at school by car．Yes，you read that correctly-the very mode of transportation that many American schools insist-the only safe way to deliver kids to school is now being criminalized in the United Kingdom．
The decision to fine any vehicles seen dropping off or picking up kids within a particular zone of east London comes from city councillors"（议员） long-term efforts to make the area safer and less crowded．They say they've been trying for years"to encourage sensible driving and parking"，but in vain．Neighborhood residents complain frequently about their driveways being blocked by illegally parked cars for 15minutes or more，often while they're trying to get to work，and the streets are long overcrowded．
Now the rules have changed．Some parents are angry．Angie Baillieul is a mother who made the"big hammer"comment and says the crackdown is"way over the top．"The nearest drop-off point for her six-year-old is now a five-minute walk from the school．Others are happy with the decision，severe though it may seem．Councillor Jason Frost said，"Traffic has significantly reduced，and more children are now walking to school，which is a great outcome．I would rather have complaints that we are slightly inconveniencing parents than hear that a child had been seriously injured because nothing was done．"
I witness daily the chaos created by these in-town drivers，when I walk my own kids to school．There's a parking lot overflowing with vehicles and a slow-moving train of cars moving in circles，many filling the air with harmful smokes．Meanwhile，the conversations around child over-weight and the importance of daily physical activity continue to stand out in schools．
