What’s not obvious is that it also assumes that exactly one row is returned! Although this is unlikely to occur for Contact, it is highly likely to occur for any custom objects you create, especially when a WHERE statement is used that might return zero rows, such as:
If you get more than 1 row and attempt to assign that to your Accountx variable you will get the opposite of your original problem - System.QueryException: List has more than 1 row for assignment to SObject! So one way of guarding against this would be to use Account accountx = [SELECT Id FROM Account LIMIT 1]'. – frup42.

Presumably the value sim is of type Car__c.You cannot assign the result of a query that returns anything other than exactly one record to a value whose type is an SObject. . In particular, this does not make sense when you're performing a search query with a LIMIT 20 clau
