since its hard to get a regular taxi to pick you up from home in the morning and from the office in the evening( or at your childrens' school), and renting a full time car and driver is quite expensive, here is a Wechat group that you could describe your requirements and find some one with similar itinerary to share a big car like Buick GL8. It helps drive the cost down for everyone. You can add this wechat ID firstly: 15800306776.
it shall be in different districts around shanghai. We are just trying to help organize groups with similar needs. Currently there is one which starts from Xuhui currently and another line starts from the century park area. welcome to add the wechat group. ID: 1442378553
