最近很多大城市都投放了共享单车(sharedbikes)，比如摩拜单车(Mobike)、Ofo共享单车等。由于它们方便停放，骑车也能起到锻炼身体的作用，作为代步工具很受大家欢迎。但是，各地也出现了很多毁车现象，比如刮掉车上的二维码(QRcode)、上私锁等。
你对这种现象怎么看?你对共享单车公司有什么建议吗?写一篇符合逻辑的英语短文，80词左右。
参考词汇：bike-sharingcompanies共享单车公司，Mobike和Ofo是两家共享单车公司，convenience方便，register登记

我对自行车共享的看法
目前，在上海和广州这样的大城市，自行车共享系统已经越来越普及。大量的共享自行车可以找到并出租低廉的价格。此外，你可以把自行车停放在你喜欢的任何地方。城市交通因此变得更加便利，甚至革命化。
然而，随着它的快速发展，自行车共享系统也带来了一些问题，包括乱停车、破坏和共享自行车的占有，等等。
为了解决这些问题，当局采取了一些措施。首先，政府可以实施更严格的法律和规则来规范自行车共享系统的操作和管理。其次，市民应合理使用共享自行车提高他们的意识。最后，城市交通系统应升级改造，以适应汽车、自行车和行人。
最后，应该对自行车共享计划采取明智的态度。通过采取有效、有效的措施和相关人员的努力，可以预期自行车共享系统将在城市公共交通中发挥积极的建设性作用。
